Given a generic tuple type T extends unknown[], write a type which produces all permutations of T as a union.

For example:

ts
PermutationsOfTuple<[1, number, unknown]>
// Should return:
// | [1, number, unknown]
// | [1, unknown, number]
// | [number, 1, unknown]
// | [unknown, 1, number]
// | [number, unknown, 1]
// | [unknown, number ,1]
