nixos containers: disable NixOS manual in container config. (#75659)

Browse source 
This makes ~2.5x speed up of an empty container instantiate, hence reduces
rebuild time of system with many declarative containers.

Note that this doesn't affect production systems much, becaseu those most
likely already include `minimal.nix` profile.

NixOS containers no longer build NixOS manual by default. This saves evaluation time,
especially if there are many declarative containers defined. Note that this is already done
when <literal>&lt;nixos/modules/profiles/minimal.nix&gt;</literal> module is included
in container config.
