Remove `audioSharingQsDialogImprovement` flag guard when injecting AudioSharingRepository.

`AudioSharingRepositoryImpl` contains general audio sharing functions (e.g, `audioSharingAvailable`), it should be injected whenever `enableLeAudioSharing` flag is on.

The dialog improvement behavior is guarded in the `AudioSharingDeviceItemActionInteractorImpl`.
