The current code looks like it's trying to redirect /integrations/doc/email
to /integrations when EMAIL_GATEWAY_PATTERN is not set.
I think it doesn't currently do this. The test for that pathway has a bug:
self.get_doc('integrations/doc-html/email', subdomain='zulip') needs a
leading slash, and putting the slash back in results in the test failing.
This redirection is not really desired behavior -- better is to
unconditionally show that the email integration exists, and just point the
user to https://zulip.readthedocs.io/en/latest/production/email-gateway.html
(this is done in a child commit).
