Given a generic tuple type T extends unknown[], write a type which produces all permutations of T as a union.
For example:
PermutationsOfTuple<[1, number, unknown]>
/**
* Should return:
* | [1, number, unknown]
* | [1, unknown, number]
* | [number, 1, unknown]
* | [unknown, 1, number]
* | [number, unknown, 1]
* | [unknown, number ,1]
*/
