CI: skip build/test jobs if only Docs/ is modified (#5387)

Could we do this to make sure that we run the GitHub Actions and Azure
jobs (build, test) only if _at least one file outside the_ `Docs`
_directory_ is modified, i.e., skip those jobs if only files in the
`Docs` directory are modified?

I think it would be safe to do so (and a bit of a waste of resources to
not do so...), but I leave it open for discussion.

If merged, we could test this rebasing #5386 and seeing if the correct
CI jobs are skipped.

Note that this PR leaves the other CI jobs untouched, e.g., `source`,
`docs`, `CodeQL`, etc.
