Added spanish translation

[ElGeroIngles]

Some translations have changed a bit in order to make more sense in spanish:

"Knives to Meet You":

• Literal translation: "Cuchillos de Conocerte"
• Spanish translation: "Encuchillado de Conocerte" (Like mixing "Encantado" with "Cuchillo")

"Josh's Cookbook":

• Literal translation: "Libro de Recetas de Josh"
• Spanish translation: "Cocinando con Josh" (May seem weird in english but it makes more sense in spanish)

"Josh's Book of Nutrition":

• Literal translation: "Libro sobre Nutrición de Josh"
• Spanish translation: "Planificación Saludable de Josh" (Both translations are right but I guess it doesn't really matters)

And probably more that I don't remember, if you want me to edit something tell me, I have already made sure that no text is left half done or cut off in the book, thanks for this amazing datapack!

I made slight adjustments, but otherwise this is perfect, thanks!
