Torjus Håkestad 04eba77ac0 fix: use nixos-version --json for configuration revision ...

- Use `nixos-version --json` command instead of reading files directly
- Add nixpkgs_rev and nixos_version labels to nixos_flake_info metric
- Show "unknown" for current_rev when system.configurationRevision not set
- Document configurationRevision setup in README
