fix: use configuration-revision for current_rev in flake info metric

Browse Source 
The nixos_flake_info metric's current_rev label was incorrectly showing
the nixpkgs input revision (from /run/current-system/nixos-version)
instead of the flake's own revision.

Now reads from /run/current-system/configuration-revision which contains
the flake's self.rev when system.configurationRevision is set in the
NixOS configuration.
