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.
This helps increase the probability that folks read the guidelines for how the
chat.zulip.org community works and what streams to use before arriving there.
Fixes#19827.
Lists API client bindings/libraries/wrappers and makes a distinction
between official core projects and community projects.
Tweaked by tabbott to sort the community and outdated libraries, and
restructure how we talk about other projects.
Fixes#2093.
