Read Maven group from GROUP property (#37204)

Summary:
The [React Native TV repo](https://github.com/react-native-tvos/react-native-tvos) shares most of the same Android code as the core repo. Beginning in 0.71, it needs to also publish Android Maven artifacts for the `react-android` and `hermes-android` libraries.

In order to avoid conflicts, it needs to publish the artifacts to a different group name. However, `react-native-gradle-plugin` uses a hardcoded group name (`com.facebook.react`).

Solution: read the group name from the existing `GROUP` property in `ReactAndroid/gradle.properties`.

## Changelog:

[Android] [Fixed] - read GROUP name in gradle-plugin dependency code

Pull Request resolved: #37204

Test Plan:
- Android unit tests have been added for the new code and new method in `DependencyUtils.kt`.
- Existing tests should pass
- The new code defaults to the correct group (`com.facebook.react`) so no functional change is expected in the core repo.
