I renamed the heading from "Social" to "Community".

Scheme and Lisp IRC, Discord, and Gitter channels are listed in the
"Chat" link under "Community" (goes to https://chat.scheme.org/).

The Scheme Reddit and Usenet newsgroups are listed under
https://lists.scheme.org/ ("Mailing lists"), which is inaccurate, but I
couldn't think of a better place to put them. Should we turn "Chat" into
general section for collecting all the community links that don't fit
elsewhere?

planet, wiki, lists are traditional subdomains on many websites, so we
should keep those for scheme.org as well. "Events" is such a big section
that it's probably best as its own subdomain as well, and
"events.scheme.org" is natural to type.
