Repositories should be added to the settings.gradle instead of allprojects

Android Studio introduced a new way to define repositories. If you have the `dependencyResolutionManagement` block in your settings.gradle, then you need to add the jitpack repository there instead of using the `allprojects` block

```
dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
...
maven { url 'https://jitpack.io' }
}
}
```

Maybe the documentation should be updated too.

Start by locating the repository setup documentation that currently instructs users to add JitPack through the allprojects block. Compare it with the dependencyResolutionManagement example in settings.gradle; done means Android Studio users with FAIL_ON_PROJECT_REPOS have clear, correct instructions for adding the JitPack repository.
