                      IOException
        Implements the transcription operation. Input parameters are (as a multipart form):
        • file: the audio stream to transcribe
        • contentType: the content type of the audio, e.g. "audio/mpeg" for mp3, "audio/wav" for wav
        • language: the language code to use, e.g. "en" for English, or null / empty for automatic detection
        • prompt: an optional prompt to give the AI some context, e.g. previous sentences
        If there is a sling suffix in the URL, we'll use it to determine the configuration. A successful response will return an HTTP 200 with the text as text/plain, UTF-8. Otherwise, it'll normally be an HTTP 400 with an error message.
        Overrides:
        doPost in class org.apache.sling.api.servlets.SlingAllMethodsServlet
        Throws:
