time-machine-2.15.0 not supported for interpreter python3.9

Just more of an fyi, but setting up a new Mac today using your WONDERFUL guide.

everything was fine until the build, seems the latest time-machine is not supported in python 3.9

I bumped to the entries in ~/nixos-config/modules/shared/packagex.nix to the following:

  python312
  python312Packages.virtualenv # globally install virtualenv

It's currently back to building just fine!
