ValueError: English is not a valid language code (WhisperX 3.1.1)

[oep42]

Surprisingly, WhisperX 3.1.1 doesn't recognize "English" as language code. (WhisperX 3.1.1 does recognize "en" as language code.)

PS C:\Windows\system32> whisperx --language=English --model=medium --output_dir=D:\Folder --output_format=srt "D:\Folder\TEST.mkv" --compute_type=int8

--language=en for english language see full language codes here https://github.com/openai/whisper/blob/248b6cb124225dd263bb9bd32d060b6517e067f8/whisper/tokenizer.py#L10

@DigilConfianz If only "en" is allowed, but not "English", then the current Help info of WhisperX should be updated.

In addition, if WhisperX would not support full language names, then WhisperX would be different from what is common among several Whisper variants — which doesn't seem like a good idea.
