rotate_right

Your mission

Implement rotate_right, a helper that rotates a list to the right.

See it in action

rotate_right([9, 8, 7, 6, 5], 2)

Expected result

[6, 5, 9, 8, 7]

Your checklist

For your own tracking. Tests grade your code.

Create right_rotate.py.
Expose def rotate_right(values: list[int], steps: int) -> list[int]:.
Return a new list containing the same values shifted to the right by steps positions.
When steps is larger than the list length, reduce it using modulo arithmetic.
Return an empty list when values is empty.
Do not mutate the input list.
