Skip updating the transcribing state when the 'audio-recording-enabled'
property is not provided.
This fixes a race when a transcriber is already in the room, we'll see
it before properties are updated (sometimes) and without checking for
undefined we'd flip the local value to false.
* fix(subtitles): Handle errors to revert to default state.
* fix(transcribing): Handle transcriber status changed.
Drops potential transcribers and hidden participant actions and handling. Expect ljm to detect transcriptions on and off.
* feat(transcriptions): Adds a notification if transcriber leaves abruptly.
* squash: Renames action.
* chore(deps) lib-jitsi-meet@latest
