feat(accessibility): Improve keyboard Access For Breakout Room Assignment

Merge pull request #12273 from mariogasparoni/fix-multiple-audio-channel-being-created-for-specific-settings

fix: prevent an extra audio channel to be created when skipCheckOnJoin is true

 fix: bug in playAudioAlert method 

fix: first audio join in breakout fails with specific config

fix: number of votes displayed in poll results annotation

Removed the wrong reference to alert.
Probably it wasn't caught by eslint because 'alert' name is also present
in browser's scope.

Closes #12228

When listenOnlyMode=false, skipCheck=true and skipCheckOnJoin=true, the
audio tries to start a session more than one time, causing it to fail
at the first one (and reconnect after that).

Now we check if user is already connecting before trying to start a new
audio session.

Added some info in settings.yml for the options related to this commit
Closes #12190

Automatically rasterize if slide contains font Type 3

When setting skipCheckOnJoin to true, an extra audio channel is created in
FreeSWITCH, after user accepts the echo test. The extra channel is removed
when user leaves the room, but this still may affect performance.
