Concatenation of vectors

Write a function that returns the concatenation of @v1@ and @v2@. That is, you must return a vector with the elements of @v1@ followed by the elements of @v2@.

C++	`vector<int> concatenation(const vector<int>& v1, const vector<int>& v2);`
Java	`public static int[] concatenation(int[] v1, int[] v2);`
Python	`concatenation(v1, v2); # returns list`
MyPy	`concatenation(v1: list[int], v2: list[int]) -> list[int]`
