[github-ci] Import run-checker daily workflow from master

The daily run-checker is scheduled to start at 6:42, instead of the
start of the hour.

The official GitHub documentation remarks the following regarding
scheduled workflows:

> Note: The schedule event can be delayed during periods of high loads
> of GitHub Actions workflow runs. High load times include the start of
> every hour. To decrease the chance of delay, schedule your workflow to
> run at a different time of the hour.

42, obviously, has been picked because it is the answer to the ultimate
question of life, the universe, and everything.
