This doesn't touch the main path through the install docs; that will
see a broader rewrite soon as we make outbound email optional for a
nascent server, make the hostname and admin email into mandatory
installer flags, and then radically simplify the instructions by
removing mandatory editing of `settings.py` and folding most of what's
left into the installer.
This adds a few missing entries to the TOC, which hadn't made sense
back when Zulip's ReadTheDocs didn't have the new collapsing feature.
Tweaked by tabbott to also give the SSL certificates doc an
appropriate title for its new role.
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.
