ci: Use Debian and Ubuntu release stage tags

Rather than use the release codename tags, use the release stage tags.
This way the configuration (theoretically) doesn't need to be updated
when new Debian and Ubuntu releases are made.

For Debian stable is used instead of buster and a testing (bullseye)
build is added. For Ubuntu, latest is used instead of focal for the
current LTS and rolling is used instead of groovy for the latest
release. This actually changes the Ubuntu build from groovy to hirsute.
