This is for preventing that a markdown button is recognized as button for submission in a html form.
Buttons can't be stripped from the markdown due to: https://codeberg.org/forgejo/forgejo/pulls/7670#issuecomment-4086608
There is no issue with buttons if they always have `type="button"`, so this should be fine.
This is a "follow-up" to !7670.
Fixes#7656
