Renamed Sonar to Flipper (#905)

* Noticed caption was "Sonar" but redirecting to https://fbflipper.com.
* Fixed caption and renamed files for consistency.
* Moved project after FastText to keep alphabetical ordering.
* Ran prettier and included changes.

Test plan:
  npm run test && npm run prettier && npm run lint

  cd website && npm run start

Noticed projects are rendered properly and caption is now "Flipper".
