[BUG] nginx request location / not /nginx-status

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Current Behavior

添加nginx监控，nginx那边配置了/nginx-status, 但是HertzBeat这边测试不通过。查看access.log发现请求的是/,而不是/nginx-status。同时修改过app-nginx.yaml中的url为/nginx-status，没有效果。

### Expected Behavior

*

### Steps To Reproduce

*

### Environment

```markdown
HertzBeat version(s): 1.4.4 使用docker部署的
```

### Debug logs

*

### Anything else?

*

Start by reviewing app-nginx.yaml and the merged pull request #1533, then reproduce the Docker-deployed nginx monitoring check against the reported configuration. Confirm that HertzBeat requests /nginx-status rather than / and verify the behavior against the issue's expected monitoring result.
