Fix flet_rive extension to work with Rive 0.14.2 update

[FeodorFitsner]

Update pubspec.lock with newer transitive package versions and checksums (cross_file, hooks, record_* packages, rive, rive_native, etc.). Adapt Rive usage in rive.dart to the newer API: replace machine.onInputChanged handlers with addAdvanceRequestListener/_onAdvanceRequested, remove the _inputHandlers list and its disposal, remove artboard.updatePass() from the advance check, and ensure advance request listeners are removed on dispose. These changes align the code with updated Rive package behavior and dependency updates.

Summary by Sourcery

Update Rive integration to be compatible with the Rive 0.14.2 API and clean up obsolete listeners and handlers.

Enhancements:

• Switch Rive state machine usage from input change handlers to advance request listeners to align with the updated Rive API.
• Simplify artboard advancing logic by relying solely on artboard.advance and removing the extra update pass.
• Ensure Rive state machines correctly unregister advance request listeners on dispose to prevent leaks and stale callbacks.

Build:

• Refresh pubspec.lock to newer transitive dependency versions and checksums for Rive and related packages.
