[Bug]: State factory module only displays in docs with workaround

[maximilianruesch]

Description

A workaround like #360 seems necessary to display the state factory module in the docs sidebar. Without that, it is not displayed:

We should investigate, and hopefully be able to revert that workaround, since it should be a proper submodule and not a reexport.

This seems to be due to autosummary_ignore_module_all = False in conf.py so that the state_factory submodule is never discovered.
