Add Debian > 9 Support

[deubert-it]

Gluster builds apt packages for Debian 10, 11 and 12 for the latest version (see https://download.gluster.org/pub/gluster/glusterfs/11/11.0/Debian/). The puppet module is capped to only support Debian up to version 9 with a hard-coded check on the codename ('jessie', 'stretch').

We patched the module and tested the modules general functionality with Debian 11 successfully, so it might be a good idea to extend the apt based compatibility for newer Debian versions.
