feat(tvix/cli): Extend nixpkgs eval test to include NixOS installer r/8503

The tvix-cli tests now include evaluating the NixOS GNOME installer ISO
image and making sure that its drvPath and outPath matches the one
evaluated by Nix. (This required extending the helper function a bit and
adding docs).

NixOS docs generation is disabled for now, see comments in diff.
