React-native-firebase: [🐛] Overriding Android Firebase BoM doesn't work

Issue

I'm trying to override Android Firebase BoM version to 25.12.0 using this code in my /android/app/build.gradle file

project.ext {
  set('react-native', [
    versions: [
      // Overriding Build/Android SDK Versions
      android : [
        minSdk    : 16,
        targetSdk : 29,
        compileSdk: 29,
        buildTools: "29.0.3"
      ],

      // Overriding Library SDK Versions
      firebase: [
        // Override Firebase SDK Version
        bom           : "25.12.0"
      ],
    ],
  ])
}

after running react-native run-android and then ./gradlew app:dependencies I'm getting the same old BoM version as if I didn't override anything

tried to put the code in different lines in the gradle file, but none of them worked

** editing @react-native-firebase/app/package.json and changing the BoM version directly works correctly

This is how I do it - I'm certain it works, it may be the documentation is slightly off on where to put it?

Thanks, the problem is in the documentation indeed.
The documentation mentions to add the code to /android/app/build.gradle which won't work
it should be added to /android/build.gradle instead

I will send a PR to fix this issue
