Restore the default django.utils.log.AdminEmailHandler when
ERROR_REPORTING is enabled. Those with more sophisticated needs can
turn it off and use Sentry or a Sentry-compatible system.

Users can, quite understandably, assume that upgrading Zulip upgraded
the underlying PostgreSQL version. Though it is mentioned at the top
of the page, mentioning it here clarifies that it is an additional
step.

Previously, `X-Forwarded-Proto` did not need to be set, and failure to
set `loadbalancer.ips` would merely result in bad IP-address
rate-limiting and incorrect access logs; after 0935d388f0, however,
failure to do either of those, if Zulip is deployed with `http_only`,
will lead to infinite redirect loops after login. These are
accompanied by a misleading error, from Tornado, of:
Forbidden (Origin checking failed - https://zulip.example.com does not match any trusted origins.): /json/events
This is most common with Docker deployments, where deployments use
another docker container, such as nginx or Traefik, to do SSL
termination. See zulip/docker-zulip#403.
Update the documentation to reinforce that `loadbalancer.ips` also
controls trust of `X-Forwarded-Proto`, and that failure to set it will
cause the application to not function correctly.

04cf68b45e make nginx responsible for downloading (and caching)
files from S3. As noted in that commit, nginx implements its own
non-blocking DNS resolver, since the base syscall is blocking, so
requires an explicit nameserver configuration. That commit used
127.0.0.53, which is provided by systemd-resolved, as the resolver.
However, that service may not always be enabled and running, and may
in fact not even be installed (e.g. on Docker). Switch to parsing
`/etc/resolv.conf` and using the first-provided nameserver. In many
deployments, this will still be `127.0.0.53`, but for others it will
provide a working DNS server which is external to the host.
In the event that a server is misconfigured and has no resolvers in
`/etc/resolv.conf`, it will error out:
```console
Error: Evaluation Error: Error while evaluating a Function Call, No nameservers found in /etc/resolv.conf! Configure one by setting application_server.nameserver in /etc/zulip/zulip.conf (file: /home/zulip/deployments/current/puppet/zulip/manifests/app_frontend_base.pp, line: 76, column: 70) on node example.zulipdev.org

This better presents the CSS organization for readers, and also
removes a stale reference and link to Bootstrap.
Because postcss-nesting's spec-aligned syntax has tripped up some
contributors, the mention of PostCSS now includes a link to the
postcss-nesting README and the CSS Nesting spec from the W3C, which
PostCSS Nesting attempts to adhere to.
