Ahora creamos un modelo `HeroCreate`, este es el que **validará** los datos de los clientes.

Tiene los mismos campos que `HeroBase`, y también tiene `secret_name`.

Ahora, cuando los clientes **crean un nuevo héroe**, enviarán el `secret_name`, se almacenará en la base de datos, pero esos nombres secretos no se devolverán en la API a los clientes.
