Tox v4 just released and has a number of breaking changes. One of which
(yet to be properly identified) has completely broken Zuul's tox
siblings processing and produces errors like:

Let's pin tox for now and a change that removes the pin can also fix tox
siblings (the change to remove the pin should be self testing
thankfully).
Also we make the zuul-tox-docs job temporarily non voting as it runs
ensure-tox non speculatively out of the opendev/base-jobs repo. We have
plenty of tox jobs runing against this changeto show it should work
fine.
