/**
* Removes elements from the end of an array until the predicate returns false.
*
* This function iterates over an array and drops elements from the end until the provided
* predicate function returns false. It then returns a new array with the remaining elements.
*
* @template T - The type of elements in the array.
* @param array - The array from which to drop elements.
* @param predicate - A predicate function that determines
* whether to continue dropping elements. The function is called with each element, index, and array, and dropping
* continues as long as it returns true.
* @returns A new array with the elements remaining after the predicate returns false.
*
* @example
* const array = [3, 2, 1];
* const result = dropRightWhile(array, (item, index, arr) => index >= 1);
* // Returns: [3]
