Zulip Server 4.0 is now 22 months old, which is more than 18 months.
Per the general policy in the "Client apps" section below, that
means it's time to drop support for older versions.
We released 5.0 near the end of 2022-03, so near the end of 2023-09
we can update this further to say 5.0.
We should rearrange Zulip's developer docs to make it easier to
find the documentation that new contributors need.
Name changes
Rename "Code contribution guide" section -> "Contributing to Zulip".
Rename "Contributing to Zulip" page -> "Contributing guide".
Organizational changes to the newly-named "Contributing to Zulip":
Move up "Contributing to Zulip", as the third link in sidebar index.
Move up renamed "Contributing guide" page to the top of this section.
Move up "Zulip code of Conduct", as the second link of this section.
Move down "Licensing", as the last link of this section.
Move "Accessibility" just below "HTML and CSS" in Subsystems section.
Update all links according to the changes above.
Redirects should be added as needed.
Fixes: #22517.
Zulip Server 3.0 is now about 21 months old, which is more than
18 months. Per the general policy in the "Client apps" section
below, that means it's time to drop support for older versions.
We released 4.0 in 2021-05, so around 2022-11 we can update this
further to say 4.0.
This uses the myst_heading_anchors option to automatically generate
header anchors and make Sphinx aware of them. See
https://myst-parser.readthedocs.io/en/latest/syntax/optional.html#auto-generated-header-anchors.
Note: to be compatible with GitHub, MyST-Parser uses a slightly
different convention for .md fragment links than .html fragment links
when punctuation is involved. This does not affect the generated
fragment links in the HTML output.
Fixes#13264.

We recently changed /developer-community to /development-community.
Now that this change is in production, we can also migrate the
external links in our ReadTheDocs documentation.
The links we have now redirect to "My groups" and not to our
Google group. Also, the RSS feed is no longer supported by Google,
so we should no longer link to it.
Fixes#19560.
This new pages accomplishes several interrelated things:
* Documents that Zulip Cloud runs master and how that works.
* Documents policies on how long client apps are expected to support
old releases in our compatibility matrix.
* Removes the 3-years-stale roadmap article.
* Provides a central place to talk about different versions in Zulip.
* Provides a better place to link to from our "you need to upgrade" nag.
This content is not intended to be final, but should be finalized in
the next week or so.
Fixes#18322.
