Enhance: Update Google Play Games integration and versioning

- Incremented version code to 3 and version name to 0.2 in build.gradle.
- Added INTERNET and ACCESS_NETWORK_STATE permissions in AndroidManifest.xml.
- Refactored leaderboard display logic in HighScoresActivity and MainActivity to utilize a listener for intent success and failure.
- Introduced silent sign-in functionality for Google Play Games in MainActivity.
- Updated GooglePlayGamesManager to support the new listener interface for leaderboard intent handling.
- Added Google Play sign-in buttons in both portrait and landscape layouts for improved user interaction.
