Actions are out of date

[jsoref]

You're using a whole bunch of outdated actions -- many of which trigger deprecation warnings.

There are also cases of stale comments that make no sense, e.g.:

gh-aw/.github/workflows/copilot-maintenance.yml

Line 31 in b50d258

# v4.2.2

These changes would more or less do the right thing, but again, this repository doesn't take external PRs:
