Add support for JSON commands in Async Cluster

[baltika10]

Version: 4.5.1
Platform: Python 3.11 on Windows 11

from redis.asyncio.cluster import RedisCluster
client = RedisCluster()
await client.json().get("test")

raises AttributeError: 'RedisCluster' object has no attribute 'json'

Actually, it's a duplicate of #2234 which was closed without real solution

Hi,

This issue does not seem fully resolved, this code still crashes:

import asyncio
from redis.asyncio.cluster import RedisCluster  # type: ignore
import redis.asyncio as redis  # type: ignore

async def main():
    r = RedisCluster.from_url("redis://localhost:16379/0")
    p = r.pipeline()
    p.json().set("blah", ".", 1)
    await p.execute()
    print("done")

loop = asyncio.new_event_loop()
asyncio.set_event_loop(loop)
asyncio.get_event_loop().run_until_complete(main())

I hacked up some changes that seem to make this pass, but it's obviously not what it should look like and I don't know if there are other situations that could be problematic: cf3bcdc
