This change adds a note and a few lines of configuration settings for Apache users to disable ModSecurity for Synapse's virtual hosts. With ModSecurity enabled and running with its default settings, Matrix clients are unable to send chat messages through the Synapse installation. With this change, ModSecurity can be disabled only for the Synapse virtual hosts.

This PR adds a information about forwarding `/_synapse/client` endpoints through your reverse proxy. The first of these endpoints are introduced in https://github.com/matrix-org/synapse/pull/8004.

I'm pretty sure there's no technical reason these have to be distinct server blocks, so collapse into one and go with the more terse location block.

also a small clarification to nginx

The specific headers that are passed using this new configuration format
are Host and X-Forwarded-For, which should be all that's required.

Note that for production another matcher should be added in the first
section to properly handle the base_url lookup:
reverse_proxy /.well-known/matrix/* http://localhost:8008

Converting some of the rst documentation to markdown.  Attempted to
preserve whitespace and line breaks to minimize cosmetic change.
