TOC does now show automatic generated sub-sections

[hagenw]

I can reproduce this locally when upgrading to the latest sphinx version.
So i guess this is a new feature.

It was introduced in sphinx-doc/sphinx#6316 (sphinx 5.2.0), and after complains they also added a config setting to be able to disable it: nocontentsentry and toc_object_entries (sphinx 5.2.3).

I would propose for the short term to disable it.

For the long-term we could use it to generate better TOCs as I always wanted to add a way to include the possibility to select a method in the TOC. The way I had in mind was to change to a structure used by pandas and numpy with having single pages for the classes, e.g. https://pandas.pydata.org/docs/reference/api/pandas.Series.html but the downside wis that this would break all existing links. So maybe we could use this new feature to work around this and stay with our current structure.
