Add bindings for com.google.mediapipe:tasks-genai Maven artifact

[Copilot]

This PR adds .NET for Android bindings for the com.google.mediapipe:tasks-genai Maven artifact, which provides Google's MediaPipe GenAI tasks functionality for Android applications.

Changes Made

Added a new artifact entry to config.json for the MediaPipe GenAI tasks library:

• GroupId: com.google.mediapipe
• ArtifactId: tasks-genai
• Version: 0.10.25 (latest available from Google Maven repository)
• NuGet Package: Xamarin.Google.MediaPipe.Tasks.GenAI
• Type: xbd (Android binding project)

The artifact follows the repository's established naming conventions and is positioned alphabetically in the configuration file between com.google.j2objc and com.google.mlkit groups.

Testing

The binderator tool successfully generated the binding project without errors, confirming that the Maven artifact is accessible and the configuration is valid.

This addition enables .NET developers to use Google's MediaPipe GenAI capabilities in their Android applications through the standard Xamarin.AndroidX NuGet package ecosystem.
