python/pdm: hide groups as implementation detail

The most important feature of the groups module was the overriding which is a separate module now. Therefore removing the fact that groups are used from the docs to decrease the API surface to maintain.

Instead render the override and overrideAll options in the manual of pdm correctly by setting `overrideType`.
