Regression: Complex factor conditions (including negative factor conditions) completely omitted from recent (v4?) docs

[posita]

Issue

From https://tox.wiki/en/3.27.1/config.html#complex-factor-conditions :

Sometimes you need to specify the same line for several factors or create a special case for a combination of factors. ... They have all been added only to help demonstrate the following:

* how factor expressions get expanded the same way as in envlist
* how to use negated factor conditions by prefixing negated factors with !
* that the order in which factors are hyphenated together does not matter

An equivalent section seems to be completely absent from https://tox.wiki/en/latest/

PR welcome.

This likely goes beyond that single section. You might want to audit how much of your documentation was lost along the way. In my experience, the former docs were much more navigable/readable.
