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.
Recommonmark is no longer maintained, and MyST-Parser is much more
complete.

This document is mainly an answer to a set of questions other
developers have been asking about Zulip's architecture and scalability
design. It's intended for developers working on Zulip, to help with
thinking about where to prioritize further efforts to optimize
scalability.
