当dubbo.provider.token =true 时，接口文档功能无法用，需要调整为false才能看到具体接口

- [ ] I have searched the [issues](https://github.com/apache/dubbo-admin/issues) of this repository and believe that this is not a duplicate.
- [ ] I have checked the [REAMDE](https://github.com/apache/dubbo-admin/blob/develop/README.md) of this repository and believe that this is not a duplicate.

### Environment

* Dubbo Admin version:0.6.0，dubbo 3.1.8-3.2.7
* Registry center detail (type and version): nacos 2.1
* Operating System version: linux
* Java version: 1.8u202

### Steps to reproduce this issue

1. org.apache.dubbo.apidocs.core.providers.IDubboDocProvider:v1:apiDocsGroup 服务，带有token发布到nacos；
2. dubbo-admin接口文档->加载接口列表 按钮，点击能访问到具体得服务方，但是服务方会返回无效得token错误；
3. 配置关闭token支持，则能够看到接口文档。

Reproduce the issue with Dubbo 3.1.8–3.2.7, Nacos 2.1, and org.apache.dubbo.apidocs.core.providers.IDubboDocProvider:v1:apiDocsGroup published with token support. Start from the dubbo-admin interface-documentation “load interface list” flow and compare the request with token enabled and disabled. Done means the service’s interface documentation loads successfully while token support remains enabled.
