Python3-tk inclusion in base image

Before opening up a pull request to the eos-meta repository, i would love to discuss the inclusion of python3-tk in the base image.

As python3 is available in the base package, i assume that many/some technicaly inclined users are using the pip facility to install libraries and tools they use to automate their workflow. However, one key component, namely Tkinter is missing from the default installation and can’t be installed by simple means. Including it would open up a bunch of new possibilities.

Currently the only way to run Python scripts which use Tkinter as their gui is inside a podman container, which in general works, but is kinda cumbersome, especially as its harder to integrate those apps with the desktop.
