In addition to many small edits for formatting and clarity, a few more
significant changes:
* In the main instructions, refer specifically to restarting the
server and to testing that the config works.
* Add SendGrid to the recommended list, as it seems like people
give it a somewhat stronger reputation these days than Mailgun.
* Discuss EMAIL_USE_TLS and EMAIL_PORT along with host, user, and
password in the "free services" section. Though those bullets feel
kind of duplicative to me already.
Let's get right to the point of how to configure SMTP once you know
what you want. That section is pretty short anyway; and we can have
a first step direct the reader to our suggestions if they don't know
what service they want to use.
Also adjust the hierarchy of the headings: group the various
alternative email services under one heading, and group
troubleshooting together under an independent heading.
Also correct what we say about EMAIL_PORT: the Django default is
apparently 25, so if the provider *does* use the usual port 587
then we'll need the port to be set.
This commit helps reduce clutter on the navigation sidebar.
Creates new directories and moves relevant files into them.
Modifies index.rst, symlinks, and image paths accordingly.
This commit also enables expandable/collapsible navigation items,
renames files in docs/development and docs/production,
modifies /tools/test-documentation so that it overrides a theme setting,
Also updates links to other docs, file paths in the codebase that point
to developer documents, and files that should be excluded from lint tests.
Note that this commit does not update direct links to
zulip.readthedocs.io in the codebase; those will be resolved in an
upcoming follow-up commit (it'll be easier to verify all the links
once this is merged and ReadTheDocs is updated).
Fixes#5265.
