Instantiated NixOS configurations. Used by `nixos-rebuild`.
`nixosConfigurations` is for specific machines. If you want to expose
reusable configurations, add them to [`nixosModules`](#opt-flake.nixosModules)
in the form of modules (no `lib.nixosSystem`), so that you can reference
them in this or another flake's `nixosConfigurations`.
