[Xamarin.AndroidX.Media3.Session] fix OnGetSeesionFromMediaLibraryService typo (#1198)

Fixes: #1195

Fixed a typo in the managedName attribute for the
`MediaLibraryService.onGetSession` method binding where "Session" was
misspelled as "Seesion". This was causing build errors when developers
tried to override the method with the correct spelling.

## Problem

When developers attempted to override the
`OnGetSessionFromMediaLibraryService` method (with correct spelling),
they would get Java errors during build. However, using the misspelled
version `OnGetSeesionFromMediaLibraryService` would compile but not
build properly.

## Solution

- Changed `OnGetSeesionFromMediaLibraryService` to
  `OnGetSessionFromMediaLibraryService` in
  `/source/androidx.media3/media3-session/Transforms/Metadata.xml`
- This is a minimal, single-character fix that corrects the typo
  without affecting any other functionality
- Removed the problematic `managedReturn` and `managedOverride`
  attributes from lines 56-67 in Metadata.xml. These were forcing the
  `onGetSession` method to return `MediaSession` instead of the
  correct `MediaLibrarySession` type, causing the Java compatibility
  errors.

Now developers can properly override the method using the correct
spelling:

```csharp
public override MediaLibrarySession OnGetSessionFromMediaLibraryService(MediaSession.ControllerInfo controllerInfo)
{
    // Implementation
}
```
