CI: replace/update Ruby components for managing deb/rpm

[pda]

We should replace or update Ruby components in CI/CD pipeline for deb/rpm packages.

Perhaps there's some non-Ruby tooling that would make it easier. Or perhaps we should at least replace the long-unmaintained https://rubygems.org/gems/deb-s3 with the less-recently-unmaintained https://rubygems.org/gems/deb-s3-patched after some security due-diligence on the latter.
