Modify update script to update matrix

[maresb]

Now that there is a matrix from #28, we should modify the update script so that the matrix is kept up-to-date.

I am on it!

Any idea why only one image is pushed though?

[maresb]

I think it's because #28 didn't update the tags according to the base image, so I think the second-built image clobbered the first-built. We should fix that... 😁

I do not understand the tagging very well.

I opened #31 which updates the image tags correctly.

Ya, the combined workings of docker/metadata-action and docker/docker-push-action are pretty opaque.

type=sha,enable=true,prefix=git- means f"git-{short_sha}" and type=raw,value=latest means "latest", and those get referenced for the push via tags: ${{ steps.meta.outputs.tags }}.

What would you like to be the tag of the cuda image?

[basnijholt]

OK I see!

What about #32?
