Update nixos-module.nix

flipping serviceConfig.Restart to "yes"

In nixos theres problems because the service is not restarting by default, and have to unplug/replug, or completely reboot the computer.

I suppose this should be free of unintended consequences—thanks!

I get the following error on rebuilding my config:

error: A definition for option `systemd.services.<...>.serviceConfig' is not of type `attribute set of (systemd option)'. Definition values:
       - In `/nix/store/dg9njr183vi6hmayn56wk7ls203yr8ki-source/nix/nixos-module.nix':
           {
             Nice = -20;
             Restart = "yes";
             SupplementaryGroups = [
               "input"
           ...

I think "yes" is not a valid value for the Restart= config option. See man

Instead of yes this should be changed to always
