Stardew valley: Fix Queen of Sauce Cookbook conditions (#3651)

* - Extracted walnut logic to a Mixin so it can be used in content pack requirements

* - Add 100 walnut requirements to the Queen of Sauce Cookbook

* - Woops a file wasn't added to previous commits

* - Make the queen of sauce cookbook a ginger island only thing, due to the walnut requirement

* - Moved the book in the correct content pack

* - Removed an empty class that I'm not sure where it came from
