pyupgrade rule for Unpack

[fzimmermann89]

It seems ruff is missing asottile/pyupgrade#745 G[Unpack[T]] => G[*T] to change UNPACK to asterisk if supported by the python version:

from typing import Unpack
def f(*x: Unpack[tuple[int, ...]]):
    return x

should be rewritten as

def f(*x: *tuple[int, ...]):
    return x
