Make Docker images generated by GitHub CI workflows available; minor CI fixes

[mkoeppe]

They are already tagged with meaningful names and just need to be pushed to a registry.

Now we push them to the registry provided by GitHub.
Example: https://github.com/mkoeppe/sage/runs/604103405 created https://github.com/mkoeppe/sage/packages/193111

Depends on #29341
Depends on #29534
