Subject: [PATCH] fix(redis): use await asyncio.sleep() instead of time.sleep()
 in async generator (#25823)

time.sleep() inside the _wrap_async_gen() async generator blocks the
entire event loop during Sentinel failover retries. The sibling method
_wrap_async_call() already correctly uses await asyncio.sleep().
