### Environment

Windows

### EventMesh version

master

### What happened

The relevant code is as follows：

//method: findEventMeshInfoByCluster
List instances =
namingService.selectInstances(eventMeshName + "-" + key, configuration.eventMeshCluster, Collections.singletonList(clusterName),
true);//Notice the second parameter here

//method register
namingService.registerInstance(eventMeshName, eventMeshRegisterInfo.getProtocolType() + "-" + NacosConstant.GROUP, instance); //Notice the second parameter here

No information can be queried by cluster

### How to reproduce

The relevant code is as follows：

//method: findEventMeshInfoByCluster
List instances =
namingService.selectInstances(eventMeshName + "-" + key, configuration.eventMeshCluster, Collections.singletonList(clusterName),
true);//Notice the second parameter here

//method register
namingService.registerInstance(eventMeshName, eventMeshRegisterInfo.getProtocolType() + "-" + NacosConstant.GROUP, instance); //Notice the second parameter here

No information can be queried by cluster

Locate the Nacos registry plugin implementations of findEventMeshInfoByCluster and register, then compare the cluster and group arguments shown in the issue. Reproduce the cluster lookup on Windows with the master version and verify that instances registered by register can be returned by findEventMeshInfoByCluster.
