Comparing .drv files appends .drv prefix to all versions

[diogotcorreia]

It appears dix already supports comparing two .drv files (e.g., dix /nix/store/7iljc0gc1k0qa047922nhh5i540r1m62-nixos-system-phobos-25.11.20260504.41a7bd5.drv /nix/store/jw2flz83fkv1q0k6a9lam625z7h8k2p4-nixos-system-phobos-25.11.20260505.0c88e1f.drv)

However, all the versions in the output include .drv:
