Subject: nixos/manual: remove md-to-db

with manual chapters no longer needing pandoc for their conversion to
xml we can get rid of this source of confusion, and its huge cache of
xml files.

-  <title>Warnings and Assertions</title>
-  <para>
-    When configuration problems are detectable in a module, it is a good
-    idea to write an assertion or warning. Doing so provides clear
-    feedback to the user and prevents errors after the build.

-    Although Nix has the <literal>abort</literal> and
-    <literal>builtins.trace</literal>
-    <link xlink:href="https://nixos.org/nix/manual/#ssec-builtins">functions</link>
-    to perform such tasks, they are not ideally suited for NixOS
-    modules. Instead of these functions, you can declare your warnings
-    and assertions using the NixOS module system.
