bump Android Gradle Plugin to 4.1.0 (#30201)

Summary:
Android Studio 4.1 release with Android Gradle Plugin 4.1.0, thus I expect developers will update to newer version and expect React Native support. Thus release include many fixes and improvements, see[release notes](https://developer.android.com/studio/releases/gradle-plugin#4-1-0), but most importantly Google released it's API documentation at https://developer.android.com/reference/tools/gradle-api. We lacked the API documentation to develop proper React Gradle Plugin.

## Changelog

[Android] [Changed] - bump Android Gradle Plugin to 4.1.0

Pull Request resolved: https://github.com/facebook/react-native/pull/30201

Test Plan: RNTester builds and runs as expected, also my apps.
