This is easy now, so make it known to admins who are looking for a
fast path for a test install.
Also totally cut the painfully complicated steps for generating a
self-signed cert by hand. Anyone who actually wants that can find a
hundred explanations on the Web, or can look at our script if they
want to specifically mirror how we do it (which is mercifully much
simpler than this.)
Bulleted information instead of prose, huzzah! Also I think we need
to explain the options a bit right here, or at least link to where
they're documented somewhere. (If the list gets much longer, we'll
want to shift toward the latter.)
Also reorganize existing information a bit, and clean up a couple
of nits.
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.
