Drop the release-artifacts (.deb packages) CI job (#272)

Follow-up to #203. In that issues we've found out that the built packages don't work correctly on some Debian versions.

We've (@mcginty I think?) when manually removed them from the 1.5.4 release artifacts, and they have been provided by 3rd party repositories since.

So drop the CI jobs.
