Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/32140
This diff is setting up the Gradle wrapper inside packages/react-native-gradle-plugin/.
Currently the `./gradlew` file is missing so it's not possible to `cd` inside the project and build it from
there (also opening that folder inside the IDE will trigger the creation of the files I added here).
This diff is fixing. The files have been generated with the command:
```
gw -p packages/react-native-gradle-plugin wrapper --gradle-version 7.0.2 --distribution-type=all
```
