Please help python find this tkinter in GUIX.

Hi,

I think you are missing the python output that has tkinter.

If you `guix show python`:

version: 3.11.11

In the outputs field you see `tk`.

You need to `guix install python:tk` in order to get it. It's not easy 
to find.

Let me know if that fixes the problem.
