- [x] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate.

### Environment

* Dubbo version: 3.1.11
* Operating System version: MAC
* Java version: 1.8

### Steps to reproduce this issue

1. 使用3.1.11的版本定义一个接口提供服务，接口中包含相同名字不同参数的X个方法，那么在provider的url上methods参数就会有多个重复的方法名
2. 在2.6.x的consumer端引用该服务时，methodInvokerMap会根据相同方法名存放X个重复invoker地址，如果默认使用random负载均衡，相当于该provider有着X倍的权重一样，压力会是X倍
3. 在刚升dubbo3的时候，如果一台机器收到的流量是其他机器的X倍，可能压力较大会有风险

Pls. provide [GitHub address] to reproduce this issue.

### Expected Behavior

在生成provider url的methods参数时，去掉重复的方法名

### Actual Behavior

同名不同参数的方法名，会在url上生成多次
