Describe the feature or problem you’d like to solve

Closing a PR without a comment seems rude 😅

Now that I think about it: gh pr comment would also be useful.

--comment "my comment" may make sense for simple one liners.
--comment and than open my code editor of choice would also be useful.

Proposed solution

gh pr close {<number> | <url> | <branch>} --comment "superseded by #123"
