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.

-        A large number of packages have been converted to use the

-        required disk space, as mentioned above. This may require
-        changes to any custom packages to make them build again; see the
-        relevant chapter in the Nixpkgs manual for more information.

-        Previous versions of Nixpkgs had support for all versions of the
-        LTS Haskell package set. That support has been dropped. The
-        previously provided <literal>haskell.packages.lts-x_y</literal>
-        package sets still exist in name to aviod breaking user code,
-        but these package sets don’t actually contain the versions
-        mandated by the corresponding LTS release. Instead, our package
-        set it loosely based on the latest available LTS release, i.e.
-        LTS 7.x at the time of this writing. New releases of NixOS and
-        Nixpkgs will drop those old names entirely.
