Use an empty item in the `New Rules` section as a marker for the GitHub
Action. If this causes problems, we could look into other solution such
as writing 2 lines before `### Bug Fixes`. But I think this is the
easiest I can come up with. So lets give it a try.
This makes it a bit easier to check if all milestoned issues/PRs are addressed, or reassign to a new milestone.
I am committing directly to master as this is a minor change which doesn't need review.
