Describe the feature or problem you’d like to solve

As part of CI, I'd like to drop a comment with the metrics of the PR.
For example like codecov does with coverage report.

As the PR is updated, I'd like to delete my initial comment and create a new one, or update my original comment.

Proposed solution

comment commands should support accepting a comment reference for example --update issuecomment-123123123 and update the comment instead of creating a new one.

--json comments should include comment IDs to be able to query them via jq.
