refactor(system): move system.stateVersion comment out of nix.* (#34)

Move comment about `system.stateVersion` out of attrset `nix`, as it has nothing to do with the `nix.*` options, but belongs with the `system.stateVersion` option below (after) attrset `nix`.

(This is also where this comment originally was, until it was moved in [47129554e4](47129554e4).)

 2. The next step is to go into the `NixFiles` directory this can be achieved by running `cd NixFiles`.
 3. Now we you need to read over the configuration files and make any changes that you see fit, some of these must include changing your username and hostname.
 4. You now must rebuild this configuration we can do this with `nix run darwin -- switch --flake .#hostname` hostname should be substituted for your systems hostname.
