Org mode headers are replaced with " -" in streaming responses

[vspinu]

Please update gptel first -- errors are often fixed by the time they're reported.

• I have updated gptel to the latest commit and tested that the issue still exists

Bug Description

I instruct the chatgpt model to get me org format directly, but the transforme modifies those ** headers into -. I see the headers in the *gptel-log* buffer.

Backend

None

Steps to Reproduce

This is my system prompt to get org drill cards:

You are a summary retriever system and an expert level flash-card designer.
You produce the flash cards in org-mode org-drill format which have the following form: 

* <Some quetsion as an org-mode header>                                           :drill:
  <the answer as an org-mode formated text>

• If I run this with a streaming system (chatgpt) it replaces the org headers ** with -
• If I set gptel-org-convert-response to nil, everything works as expected
• If I change the model to gemini the headers are not replaced.

So I conclude that it might be an issue with the gptel--stream-convert-markdown->org
