refactor(rome_formatter): Delete FormatElement::Comment

This PR removes the `FormatElement::Comment` element. It was used to this point because the `group` builder had to move `comments` outside of the start/end of the group.

No such inspection is necessary after the refactor which is why the element can be deleted.
