Subject: [PATCH] Fix tox-docs failing sphinx

A new version of sphinx was released May 29 2022
which requires a language setting in config otherwise
a warning (treated as error) causes the sphinx operation
to fail.

Updated the sphinx config file to correct the issue.

The sphinx behavioural change is mentioned here:
