Hello, I am a beginner in eventmesh. Upon seeing the problem described in this issue, I wonder if eventmesh has already been refactored. I couldn't find the location of eventmesh-registry-zookeeper, but I found one located in eventmesh metaeventmesh-meta\eventmesh-meta-zookeeper\src\main\java\org\apache\eventmesh\meta\zookeeper\service\ZookeeperMetaService. Do I need to modify it here?

Meanwhile, regarding the document "Quick Start", I think the description of meta (Registry Meta Service) is too simple. I only understood it based on the code. Can I try to improve the Chinese description of Quick Start in the document?（https://eventmesh.apache.org/zh/docs/instruction/runtime）

Yes, the location may have changed due to updates to the code module, this looks unfinished, welcome to the eventmesh community.
