unify version string between lix and nixos-module

Currenlty `lix` and `nixos-module` have slightly diverging version
numbering. This commit fixes the lix side of things, in accordance to
the format proposed in
https://git.lix.systems/lix-project/lix/issues/585#issuecomment-7336
which allows for better use of `builtins.compareVersions`

fixes #585
