- feat: merge `next-on-netlify` into `@netlify/plugin-nextjs`

  This improves our ability to maintain the plugin, reduces confusion about how to configure Next.js support for Netlify builds, and prepares the plugin for something we're pretty dang excited about: automatic installation for new Next.js projects!

> **NOTE: There are no breaking changes for existing plugin users.** This is a major release because we're bringing an external package into the plugin _and_ turning on automatic installation for new Next.js projects on Netlify. This doesn't break anything, but it's a big enough change that we wanted to treat it as a major release.

- fix: next 10.0.8 changes loadConfig to be async ([#105](#105))
