This PR enables the dependabot to automatically check for updated GitHub Actions versions every quarter and send PRs with any updates. This removes the burden from us to maintain up-to-date versions.
I mistakenly thought this had to be done via the repository Settings. But no, that just opens an editor in the UI to create the file
.github/dependabot.yml. In other words, there is no advantage to that option compared to directly adding the file via a PR.xref: #362 (review)
