fix(apt): Update Debian repo handling for Debian 13

We're now using the built-in deb822_repository module to handle
Debian package repositories. We no longer need individual yml files
per repo and instead perform just one loop call of the
deb822_repository module. We also update repo content to Proxmox VE 9
and Debian 13.
