/**
* Creates a predicate that checks whether the piped array is a subset of superset.
*
* Every value in the piped array must be present in superset, using the main
* {@link isSubset} equality behavior.
*
* @template T - The type of elements in the arrays.
* @param superset - The array that may contain all values from the piped array.
* @returns A predicate for the piped array.
*
* @example
* import { isSubset, pipe } from 'es-toolkit/fp';
*
* pipe([1, 2], isSubset([1, 2, 3]));
* // => true
