Improve with-algolia-react-instantsearch example and convert to TypeScript (vercel#42617)

Converted to TypeScript to match Contribution docs, and updated/simplified the example.

- Replaced stylesheets in Head component with imported styles
- Removed `style-loader`, `css-loader`, `cross-env`, `prop-types` packages
- Removed custom webpack config

## Documentation / Examples

- [X] Make sure the linting passes by running `pnpm build && pnpm lint`
- [X] The "examples guidelines" are followed from [our contributing doc](https://github.com/vercel/next.js/blob/canary/contributing/examples/adding-examples.md)
