Add ```react-native-screens``` native configs in Android during new app initialization

Describe the Feature

Add react-native-screens native configs in Android as per described here : https://reactnavigation.org/docs/getting-started?framework=community-cli#installing-dependencies

Possible Implementations

• The native codes can be added right when a new app is initialized.
• For better performance with react-native-screens, as it is now a common part of all new @react-native-community/cli apps , so the native codes should already be there rather adding manually.

See the docs here : https://reactnavigation.org/docs/getting-started?framework=community-cli#installing-dependencies

import android.os.Bundle
import com.swmansion.rnscreens.fragment.restoration.RNScreensFragmentFactory

// ...

class MainActivity: ReactActivity() {
  // ...

  override fun onCreate(savedInstanceState: Bundle?) {
    supportFragmentManager.fragmentFactory = RNScreensFragmentFactory()
    super.onCreate(savedInstanceState)
  }

  // ...
}

import android.os.Bundle;
import com.swmansion.rnscreens.fragment.restoration.RNScreensFragmentFactory;

// ...

public class MainActivity extends ReactActivity {
  // ...

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    getSupportFragmentManager().setFragmentFactory(new RNScreensFragmentFactory());
    super.onCreate(savedInstanceState);
  }

  // ...
}

Related Issues

Sometimes linking, unnecessary whitespaces, flickers may occur if the screen navigation animation does not render properly.

Start by locating the Android initialization templates used when a new React Native app is created, including the Java and Kotlin MainActivity variants. Compare them with the react-native-screens setup described in the linked React Navigation documentation. Done means newly generated Android apps include the required native configuration without manual changes.
