doc: Incomplete Tutorial for DNS server setup?

Hello hello! I was perusing the how to section of the Server Documentation, and would like to make a note that this is the **bare minimum** setup for a DNS server. However, it seems that it's missing some things for "Sane Default Configurations" which make it comply with RFC and other DNS-important features.

Such things are "Enabling DNSSEC verification on lookups" among other 'sane defaults' such as conforming to RFC 1035 which is not part of the default standard configs, etc.

Would contributions appending useful information or such be useful? Or would you prefer there be a more in-depth description of how to do things with regards to DNS servers? (I'm willing to put together a "DNS Server Setup, Configuration, and Considerations" workshop or such if necessary as I have some pretty interesting things I do with DNS servers and BIND9 if it's interesting to have those.)

Document: how-to/networking/install-dns.md

Start with how-to/networking/install-dns.md and review the existing bare-minimum DNS setup, focusing on the requested DNSSEC verification, RFC 1035 considerations, and BIND9 practices mentioned in the issue. Before editing, establish whether the project wants appended sane defaults or a separate DNS Server Setup, Configuration, and Considerations workshop; done means the scope and documentation coverage are agreed.
