0.4.1.post1: questions about `sphinx-toolbox-experimental` and some issues

[kloczek]

https://github.com/sphinx-toolbox/sphinx-toolbox-experimental there is no yet first release and sphinx-toolbox-experimental is not refistered on pypi.
It is a bit odd that released module is using another nit released yet module 😄

Is that modulerelally needed to build extras-require documentation?
If yes: are you going to make first release of the sphinx-toolbox-experimental and register it on pypi?

[kloczek]

Here is build-shonx output where that module is required

The above exception was the direct cause of the following exception:

[kloczek]

As I don't see thet sphinx_toolbox_experimental I've decided to remove that module from pyproject.toml by:

Than on building documentation I've hit two issues.
First one that buid-shinx is not able to locate sphinxcontrib.extras_require module

Looks like here is wrong module name because it should be sphinxcontrib.extras_require
I'm not sure where that should be fixed 🤔

And at the end looks like pytest is failing
