Double hyphens (--) in PR descriptions are turned into em-dashes (—) even in the plain text markdown editor, which breaks markdown comments

Describe the issue

I noticed this issue while using PR templates, our PR template uses markdown comments for additional guidance. For example

### Section heading 
<!-- Some helpful text to clarify things for developers writing PRs -->

When I import the PR template into Gitbutler's PR editor, I noticed that the closing in these comment sections (-->) was replaced with a —> - the text editor had converted the double hyphens into em-dashes. This causes some strange rendering issues when the markdown hits Github.

I was able to replicate the issue by pasting or typing a markdown comment into the plain text editor, I've attached a screen recording to demonstrate.

How to reproduce (Optional)

1. Create a new PR from the Gitbutler UI
2. Add a markdown comment to the PR description, for example <!-- markdown comment -->
3. You should be able to see that the hyphens in at least one of the comment tags has changed to an em-dash

Expected behavior (Optional)

The plain text editor should always retain the original hyphens

Thanks a lot for reporting, the video makes the issue crystal clear!

Indeed, in the plain-text editor one would least expect such effect, apparently some smartness is still going on there. I wonder if this will also happen in the rich-text editor, but that would be my guess.

In any case, I am sure @estib-vega will make short work of it.
