/**
 * Challenge: create a new utility function called getPizzaDetail. It will take
 * a parameter called `identifier`, but there's a twist: we want this identifier
 * to be allowed to either be the string name of the pizza (e.g. "Pepperoni"),
 * OR to be the number ID of the pizza (e.g. 2).
 * 
 * Don't worry about the code inside the function yet, just create the function
 * signature, making sure to teach TS that the `identifier` parameter is allowed
 * to either be a string or a number.
