[docs] [issue35564] [DOC] Sphinx 2.0 will require master_doc variable set in conf.py

[jfbu]

New submission from jfbu <jfbu at free.fr>:

When building CPython doc with master branch of dev repo of Sphinx (future Sphinx 2.0) one gets this warning:

WARNING: Since v2.0, Sphinx uses "index" as master_doc by default. Please add "master_doc = 'contents'" to your conf.py.

Fix will be to do as Sphinx says :)
