Bug Report

When choosing Whisper (Local) as Speech-to-Text Engine and change the STT Model from base to turbo, there is an error show in docker log:

File "/usr/local/lib/python3.11/site-packages/faster_whisper/utils.py", line 78, in download_model
    raise ValueError(
ValueError: Invalid model size 'turbo', 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

It looks like the faster_whisper inside open-webui doesn't support faster-large-v3-turbo model. When checking faster_whisper model list, it already supports this turbo model. Please see the benchmark.

Installation Method
