GitHub Actions release

We need to migrate from CircleCI to GitHub Actions, and overall resurrect builds, I think they are dead.

Will this allow us to push out releases for all GDAL versions back to 3.1? That's the thing that seems to be missing.

Ouf so you want to build / back fill artifacts compatible with all the previous gdal versions released since 3.1?

Tough call! We don't have automatic support for that right now... But theoretically we could try since our Dockerfiles are parametrized now.

I think it makes sense to have automated builds for the most recent GDAL version / the most recent GDAL version we need. + to have a manual pipeline parametrized trigger to run builds for specific GDAL versions that we really need but are missing for some reason.

It is not that trivial since for every GDAL version we need to have a separate GDAL image; and GDAL image builds are not automated...

Aha. I think I assumed at that moment that these builds were taking place in an OSGeo GDAL container base that would have been easy to parameterize. I forgot that these containers are more complicated than that. Seems like the transition to GH actions would give us a moment to automate these builds. That's a bit bigger of a lift, I suppose.
