Provider服务中配置为 dubbo.application.register-mode=instance方式，dubbo-admin0.6.0获取不到nacos上的服务和接口。

Environment

• Deploy env: SpringBoot2.7.18、SpringCloud 2021.0.9、SpringCloud Alibaba 2021.0.5.0
• Dubbo application version: dubbo 3.2.19
• Registry: Nacos 2.2.3

Issue description

dubbo的Provider中使用如下配置：

dubbo:
   application:
      name: dubbo-provider
      register-mode: instance
      metadata-type: remote
      qos-enable: true
      qos-port: 35401
      dump-directory: ./logs/dubbo-dump
   metadata-report:
      address: nacos://${app.domain}:8848
      report-metadata: true
      parameters:
         namespace: dev
         group: dubbo
         username: nacos
         password: nacos
   registry:
      address: nacos://${app.domain}:8848
      username: nacos
      password: nacos
      timeout: 10000
      parameters:
         namespace: dev
         group: dubbo
         registry.register-instance-mode: instance
   config-center:
      check: false
      address: N/A
   scan:
      base-packages: com.test.provider.api
   protocol:
      serialization: hessian2
      name: dubbo
      port: 35400
   shutdown:
      timeout: 60000
   provider:
      group: dubbo
      delay: 3000
      retries: 1
   consumer:
      serialization: hessian2
      check: false
      timeout: 3000
      retries: 2
      loadbalance: roundrobin

在 Nacos注册中心的 配置管理中，有dev名称空间的group为dubbo的服务(dubbo-provider)和接口信息，服务管理中，有dev名称空间的group为dubbo的服务信息 dubbo-provider。dubbo-admin0.6.0 的服务查询只能查到自己注册的Mock服务。
在 org.apache.dubbo.admin.service.RegistryServerSync 类中加日志打印 
logger.info("=========================================");
logger.info("RegistryServerSync.notify() services=" + services);
结果也只打印了你们自己的 Mock服务。
