Maximilian Bosch 6ad5c9c17c module: use defaultText to not depend on the configuration when building the manual
I do build my workstation with `documentation.nixos.includeAllModules`
to also have private modules and external stuff in my local options'
reference.

Not sure why exactly this breaks with

    error: attribute 'loader' missing

    at /nix/store/h6qicay9fgggx9nf6apdl6zkdpdp28xx-source/module.nix:46:19:

        45|         type = lib.types.bool;
        46|         default = config.boot.loader.systemd-boot.enable || config.boot.loader.grub.efiSupport;
          |                   ^
        47|       };

but using defaultText is the usual fix that also works here.
