Help us testing 🧪

<!-- TODO Add the call to action for something specific that we want folks to test -->

RC4 is going to be the last RC before 0.70.0 - unless blocking issues arise. To help us catch them, test it by running:

<!-- TODO Update with your version --> npx react-native init RN070RC4 --version 0.70.0-rc.4

And play around with the fresh app - let us know how it went by posting a comment in the working group discussion! Please specify with system you tried it on (ex. macos, windows).

Bonus points: It would be even better if you could swap things around: instead of using a fresh new app, use a more complex one!
