[QGIS-Developer] Github actions analysis

(psc dropped because it will bounce)

As part of this, I think it would be good to consider how things might
be different after a move from github to either codeberg or self-hosted
forgejo.  I don't mean to really design that, just a background thought
of "if we (qgis.org) buy this hardware, and we later move, will we wish
we had done something different, or will we just need more, and this
will all be entirely usable, so it's fine".  I suspect it really is
fine.

16 GB sounds like low RAM for a CI machine for qgis.   I would want to
make sure it's expandable to at least 64G, and would start a bit higher.
