Mistral series responses are always wrapped in triple backticks (```)

[qixing-jk]

Body:
Description:
When using the AI to generate text (e.g., commit messages or documentation content), the output is consistently wrapped in triple backticks (```), even when plain text is expected. This makes it inconvenient to commit directly.

Expected Behavior:
The AI should return the text as plain text, without automatically wrapping it in ``` code blocks.

Observed Behavior:
All responses are wrapped in triple backticks (```), e.g.:

```
docs: update link labels in README files
- Improve clarity for language selection links
```

Additional Context:
This issue arises across various prompt types and is not confined to a specific category of text. However, it exclusively occurs within the Mistral series.
