fixed verboseJson encoding

[Frank-Buss]

What

This fixes the verboseJson encoding. I tested it with verboseJson, and works still with text as well.

Why

I got this error: Transcription failed: APIErrorResponse(error: OpenAI.APIError(message: "[{'type': 'enum', 'loc': ('body', 'response_format'), 'msg': "Input should be 'json', 'text', 'vtt', 'srt' or 'verbose_json'", 'input': 'verboseJson', 'ctx': {'expected': "'json', 'text', 'vtt', 'srt' or 'verbose_json'"}}]", type: "invalid_request_error", param: nil, code: nil))

because verboseJson was not encoded as verbose_json.

Anyone who wants to review it? I need this for my project. I can use my branch, but would be better to integrate this change, so it works for everybody. BTW, I needed it because Whisper returns nonsense for silence, which is easily fixed by testing no_speech_prob for > 0.4 with the verbose json response.
