[Bug] HStore Spring Actuator Metrics Sink Initialization once causes missing metrics

### Bug Type (问题类型)

logic (逻辑设计问题)

### Before submit

- [X] 我已经确认现有的 [Issues](https://github.com/apache/hugegraph/issues) 与 [FAQ](https://hugegraph.apache.org/docs/guides/faq/) 中没有相同 / 重复问题 (I have confirmed and searched that there are no similar problems in the historical issue and documents)

### Environment (环境信息)

- Server Version: master
- Backend: HStore

### Expected & Actual behavior (期望与实际表现)

# 期望结果
通过Spring Actuator 接口获取正确的 JRaft 监控指标
curl http://ip:8620/actuator/prometheus

# BUG 详情
HStore 节点初始化后，通过prometheus 定时拉取指标，此时会造成指标丢失
BUG根本原因是初始化仅一次，JRaft 有些埋点暂时还未注册，因此造成缺失
具体错误逻辑代码如下
```java
@Configuration
public class MetricsConfig {

@Bean
public MeterRegistryCustomizer metricsCommonTags() {
return (registry) -> registry.config().commonTags("hg", "store");
}

@Bean
public MeterRegistryCustomizer registerMeters() {
return (registry) -> {
StoreMetrics.init(registry);
RocksDBMetrics.init(registry);
JRaftMetrics.init(registry);
ProcfsMetrics.init(registry);
GRpcExMetrics.init(registry);
};
}

}
```

# 具体指标
```
