Fix container image build&push process using tags

This commit changes several things related to the build & push process:

- Use the fixed ghcr.io/mmul-it/kpa-marp-pandoc:v1.0.0 base container release.
- Use the branch name as the tag for the generated image (adding also latest).
- Push on both ghcr.io and quay.io the same container images with same tags.
