Make http://docs.citationstyles.org/ HTTPS

[rmzelle]

Requires upstream support at Read the Docs. See readthedocs/readthedocs.org#2652.

Last remaining piece of the CSL website that isn't HTTPS yet. (see also #37)

This was fixed in August 2018: readthedocs/readthedocs.org#2652 (comment)

Still waiting for Read the Docs to support automatic HTTPS redirects: readthedocs/readthedocs.org#4641

[adam3smith]

I think we can close this -- https is enabled, even if redirect isn't automated.

[rmzelle]

Sure. Not sure if we'll have to do anything once automatic redirects are offered, although we do already have "Always use HTTPS for this domain" checked for Read the Docs.
