The weekly rebuild of the CI container image for the Mingw64 builds works fine.
But the previous image versions are kept as untagged images in the container registry.
This workflow should remove all untagged image versions except that last five ones.
It is schedules weekly two hours after the image build workflow.
I'm not completely sure if it works out of the box, let's see on its first run :).
