[RFC] Remove or update MismatchBranch comment when is OK

[alamirault]

Hi,

What do you think to remove or update comment when developer fix target branch ?
What do you prefer ?

If you're ok, what is the best implementation ? (list all comments, check for botUsername author and make action if it's ok ? )

For example symfony/symfony#51217 (comment)

That's a cool idea - as a user, updating the original comment would be nicer, I think - but either approach is probably fine.

duplicate of #210 ?
