Add missing languages to configuration definitions.

XTTS supports 17 languages, and whisper supports all of those languages. This adds extra languages to the configuration. See: discord dev post.

Hello! What makes a language supported? If the XTTS is xVASynth there are more languages right? Can you educate me on the subject a little? I'm trying to make norwegian work and test around, and publish my results!

Its the 2 letter language that is used by mantella's python script for TTS and STT. What we have here is all those language supported by XTTS, but whisper should support a lot more (see https://platform.openai.com/docs/guides/speech-to-text/quickstart).

In the setup that I have, I use a different language for STT and english for TTS. So you can speak, in lets say Norwegian, and that text will get passed to the LLM, but you set the prompt so it always returns text in English, and so the TTS will read it in english. You can have a separate language for STT and another one for TTS.
