[pytest-dev] doc/docs.pytest.org now proper with https

[holger krekel]

Thanks to Florian Schulze who instantiated an nginx/letsencrypt
proxy on the planet.pytest.org pytest now serves ssl directly
(https://docs.pytest.org ) directly by proxying and reverse-proxying 
to readthedocs.org.  But we need an email admin address -- i can
create a "pytest-admin at pytest.org" alias which forwards to a 
couple of committers and we could also mention it in the
contacts page. Makes sense?
