Allow insecure and permitted insecure not having an effect

Google my way to a solution, change the let to

   let
      system = "aarch64-darwin";
      pkgs = import nixpkgs {
        inherit system;
        config = {
          permittedInsecurePackages = [ "nodejs-14.21.3" "openssl-1.1.1w" ];
        };
      };    

That in turn lead to a different problem that I am trying to get help on here: Restricting python version from nixpkgs
