feat: create github learning lab for usage of cookiecutter-python template

[martinm82]

Since the cookiecutter itself has not the ability to easily add comments during the process of generating a new project (currently it shows you only the cookiecutter variable name and possible values) it would be good to have a simple Github learning lab showing how to create easily projects.

This would then explain step by step all the available variables and show the user what exactly to do.

Is there already an open feature request comments in the cookie cutter template? Maybe it is something we could put a PR in for?

[martinm82]

There is already a huge discussion ongoing in the cookiecutter project but no outcome yet.
