enhancement: external stt

[Stargate256]

Is your feature request related to a problem? Please describe.
Would it be possible to allow running whisper on another server?

Describe the solution you'd like
Adding the ability to connect to whisper via some kind of API.

Additional context
I am running open-webui on a server without GPUs, and LLMs, TTS on another server.

I've recently developed faster-whisper-server which provides an OpenAI compatible transcription/translation (and some extras as well) which could be used as a transcription backend if OpenWebUI adds support for having an external STT

STT & TTS settings have been refactored on dev and you can now configure external OpenAI STT from Admin Settings!

I tried this and the model name for STT is not correctly used.

ValueError: Invalid model size 'whisper-1', expected one of: tiny.en, tiny, base.en, base, small.en, small, medium.en, medium, large-v1, large-v2, large-v3, large, distil-large-v2, distil-medium.en, distil-small.en, distil-large-v3
