DOC, CI: Add a "skip" option to only run docs-related CI checks
Currently, for a regular docs PR we should not skip GitHub actions since that is where the artifacts redirector job is run.
We could add a [docs only] CI option that is equivalent to running only CircleCI, i.e.
[skip azp][skip cirrus][skip travis][skip actions]
but runs the artifacts redirector job.
When using [skip azp][skip cirrus][skip travis][skip actions] on the last commit on #24138, the redirector shows up, so maybe all we need is an alias. But wouldn't processing the alias require running some CI?
Travis CI is already gone, and hopefully Azure will soon be gone to. In that case we'd need [skip cirrus] [skip actions]. That could be aliased, but that then indeed requires more logic, so it may not be worth it. In particular, on GHA we'd need a "check skip" job that runs before every other job, like we have now on Azure.
One related thing I've been thinking about is automatically checking if it's a docs-only PR, and skipping jobs based on that. It would also need trigger logic, which has the same problem as a [docs only] label. But it'd probably be more useful, since so many doc PRs are made by new contributors who aren't going to use the magic snippet in a commit message.
Any update on a [docs only] option? I've seen it show up in some commits, but don't know if it's been added yet. I love the idea of an automatic check. Is there still interest?
Let me work some more on it. I can probably make some progress this week.
