fix: unable to send audio messages on Telegram (#4493)

- Changed the lib used to record the audio (videojs-record). 
- Changed the audio recording format to .ogg, this will keep compatibility with sending to channels, Telegram, Whatsapp, Web Widget and API.
- Changed the visualization of recording waves, it is now using bars, the same format used by applications (Whatsapp and Telegram)
