chore: add starters to monorepo (gatsbyjs#10310)

This PR adds in starters to the monorepo. Longer term, I believe we'll merge starters/examples since they're very much linked.

Future implementation improvements:

- Run a `build` script to validate that the starter(s) can be built
  - I planned to use `lerna run --scope gatsby-starter-*` for this, but if there's another approach, happy to try that
- Implement yarn workspaces/lerna so we can get automatic versioning in the starters (I have this built out at https://github.com/dschau/starters)
- Author `e2e` tests vs. the starters so that we can ensure we're not breaking anything
  - These would follow a similar approach to the current e2e tests

+  Gatsby's <%= name %> starter
+</h1>
+
+Kick off your project with this <%= name %> boilerplate. This starter ships with the main Gatsby configuration files you might need to get up and running blazing fast with the blazing fast app generator for React.
+
+_Have another more specific idea? You may want to check out our vibrant collection of [official and community-created starters](https://www.gatsbyjs.org/docs/gatsby-starters/)._
+
+## 🚀 Quick start
+
+1.  **Create a Gatsby site.**
+
+    Use the Gatsby CLI to create a new site, specifying the <%= name %> starter.
+
+    ```sh
+    # create a new Gatsby site using the <%= name %> starter
+    npx gatsby new my-<%= name %>-starter https://github.com/gatsbyjs/gatsby-starter-<%= name %>
+    ```
+
+1.  **Start developing.**
+
+    Navigate into your new site’s directory and start it up.
+
+    ```sh
+    cd my-<%= name %>-starter/
+    gatsby develop
+    ```
+
+1.  **Open the source code and start editing!**
+
+    Your site is now running at `http://localhost:8000`!
+
+    \_Note: You'll also see a second link: `http://localhost:8000/___graphql`. This is a tool you can use to experiment with querying your data. Learn more about using this tool in the [Gatsby tutorial](https://www.gatsbyjs.org/tutorial/part-five/#introducing-graphiql).\_
+
+    Open the `my-<%= name %>-starter` directory in your code editor of choice and edit `src/pages/index.js`. Save your changes and the browser will update in real time!
+
+## 🧐 What's inside?
+
+A quick look at the top-level files and directories you'll see in a Gatsby project.

+    ├── node_modules

+    ├── .prettierrc

+    └── README.md
+
+1.  **`/node_modules`**: This directory contains all of the modules of code that your project depends on (npm packages) are automatically installed.
+
+2.  **`/src`**: This directory will contain all of the code related to what you will see on the front-end of your site (what you see in the browser) such as your site header or a page template. `src` is a convention for “source code”.
+
+3.  **`.gitignore`**: This file tells git which files it should not track / not maintain a version history for.
+
+4.  **`.prettierrc`**: This is a configuration file for [Prettier](https://prettier.io/). Prettier is a tool to help keep the formatting of your code consistent.
+
+5.  **`gatsby-browser.js`**: This file is where Gatsby expects to find any usage of the [Gatsby browser APIs](https://www.gatsbyjs.org/docs/browser-apis/) (if any). These allow customization/extension of default Gatsby settings affecting the browser.
+
+6.  **`gatsby-config.js`**: This is the main configuration file for a Gatsby site. This is where you can specify information about your site (metadata) like the site title and description, which Gatsby plugins you’d like to include, etc. (Check out the [config docs](https://www.gatsbyjs.org/docs/gatsby-config/) for more detail).
+
+7.  **`gatsby-node.js`**: This file is where Gatsby expects to find any usage of the [Gatsby Node APIs](https://www.gatsbyjs.org/docs/node-apis/) (if any). These allow customization/extension of default Gatsby settings affecting pieces of the site build process.
+
+8.  **`gatsby-ssr.js`**: This file is where Gatsby expects to find any usage of the [Gatsby server-side rendering APIs](https://www.gatsbyjs.org/docs/ssr-apis/) (if any). These allow customization of default Gatsby settings affecting server-side rendering.
+
+9.  **`LICENSE`**: Gatsby is licensed under the MIT license.
+
+10. **`package-lock.json`** (See `package.json` below, first). This is an automatically generated file based on the exact versions of your npm dependencies that were installed for your project. **(You won’t change this file directly).**
+
+11. **`package.json`**: A manifest file for Node.js projects, which includes things like metadata (the project’s name, author, etc). This manifest is how npm knows which packages to install for your project.
+
+12. **`README.md`**: A text file containing useful reference information about your project.
+
+## 🎓 Learning Gatsby
+
+Looking for more guidance? Full documentation for Gatsby lives [on the website](https://www.gatsbyjs.org/). Here are some places to start:
+
+- **For most developers, we recommend starting with our [in-depth tutorial for creating a site with Gatsby](https://www.gatsbyjs.org/tutorial/).** It starts with zero assumptions about your level of ability and walks through every step of the process.
+
+- **To dive straight into code samples, head [to our documentation](https://www.gatsbyjs.org/docs/).** In particular, check out the _Guides_, _API Reference_, and _Advanced Tutorials_ sections in the sidebar.

+Gatsby is a modern framework for blazing fast websites. This repository is our monorepo for managing all the great GatsbyJS starters for the community.
+
+## What's a starter?
+
+A starter is a simplified example to get up and running with Gatsby quickly and easily. These starters are directly integrated with the Gatsby Command Line Interface (CLI).

+
+## 🚀 Get Up and Running in 5 Minutes
+
+```sh
+# install the Gatsby CLI globally
+npm install -g gatsby-cli
+
+# create a new Gatsby site using the default starter
+gatsby new my-blazing-fast-site
+```
+
+e.g. `gatsby new blog my-blazing-fast-site` or `gatsby new hello-world my-blazing-fast-site` to use a specific starter!
+
+This will clone the starter of specified name into the folder `my-blazing-fast-site` and get you up and running in under 5 minutes with Gatsby and a fantastic starter. We can't wait to see what you build!

+### Code of Conduct
+
+Gatsby is dedicated to building a welcoming, diverse, safe community. We expect everyone participating in the Gatsby community to abide by our [**Code of Conduct**][code-of-conduct]. Please read it. Please follow it. In the Gatsby community, we work hard to build each other up and create amazing things together. :muscle: :purple_heart:
+
+### A note on how this repository is organized
+
+This repository is a [monorepo][monorepo] managed using [Lerna][lerna]. This means there are [multiple packages--starters!!--][starters] managed in this codebase that are independently versioned but co-exist within this repository.
+
+We have set-up read-only clones of all of the [starters][starters] in the official gatsbyjs organization. For example, the [`default` starter](starters/default) is available as a read-only clone at [`gatsbyjs/gatsby-starter-default`][gatsby-starter-default]. Please open PRs versus **this** repository rather than the read-only clones. Upon merge any starters that have been modified will be tagged and released.
