Since the Zulip API runs on both developement and production
servers, it is misleading to mention "dev servers" when discussing
zuliprc files.
Also, note that it is better to manually edit all of our JS
examples than to implement macro-like functionality that we use
for our Python examples. For our current purposes, it would be
too much work to build a full-blown testing framework for our
JS code examples just so that we can fix a minor wording issue.
Fixes#10672.
