Subject: [PATCH] github/workflows: refactor comment workflow to not use
 github-script

It is not actively maintained, third-party, javascript wrapper on GitHub
API. The v7 version has issues and most importantly, we don't need a
JavaScript interface to create a comment. Use the first-party CLI tool
and jq.

Sort artifacts by name while at it.
