AsyncIO Cluster Mode Lock doesn't work

[KMilhan]

Version: 4.3.x - 4.4.0rc2

Platform: Python 3.10 on Ubuntu 20.04

Description: AsyncIO Cluster mode doesn't seem to support Lock

Reproducible code is this

async def test_aiolock():
    from redis.asyncio.lock import Lock as ALock

    r: redis.asyncio.RedisCluster = aredis()  # Async Redis cluster connection
    counter = 0
    async with ALock(
        redis=r, name="test-lock", timeout=None, sleep=0.01, blocking=True
    ):
        counter += 1
    assert counter == 1

Log is as follow

Also, I think we can typehint async version of Lock to accept Async version of client only... now it looks like it also accepts blocking client too. (which doesn't work either with async version of Lock)
