resolves #2617

What is in this change?

Once a Transcription API is set to OpenAiWhisper, transcription result is failure whenever I upload a .mp3 file. I find that the code in line 36 of OpenAiWhisper.js in collector directory is return a result like: content: response. I have referred to the docs in openai.com, the example shows that the text content should extract by using response.text. So I change the code to content: response.text, and my question is solved.
