The Python bindings (which are used for bots, amongst other things) can
be configured either with a .zuliprc file or with environment variables
in the host machine.
This new page in the user docs explains how to set the bindings up using
both techniques, and is a good reference on the setup required by Zulip
bots.
This commit allows for the /api-new/ page to rendered similarly to our
/help pages. It's based on the old content for /api, but we're not
replacing the old content yet, to give a bit of time to restructure
things reasonably.
Tweaked by eeshangarg and tabbott.
