Add Debian package registry (#24426)
Co-authored-by: @awkwardbunny
This PR adds a Debian package registry.
You can follow [this
tutorial](https://www.baeldung.com/linux/create-debian-package) to build
a *.deb package for testing.
Source packages are not supported at the moment and I did not find
documentation of the architecture "all" and how these packages should be
treated.
