nacos-config.sh推送seata配置到nacos1.3.0上发生错误

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

### Ⅰ. Issue Description
./nacos-config.sh -h 192.168.0.104 -p 8804 -g SEATA_GROUP -t 3b964d9d-70c2-4c53-baf4-b51566f828ae -u nacos -w nacos
set nacosAddr=192.168.0.104:8804
set group=SEATA_GROUP
Please check the cluster status.
nacos1.3.0服务端日志：
2021-08-07 13:58:20,411 ERROR Servlet.service() for servlet [dispatcherServlet] in context with path [/nacos] threw exception
org.springframework.security.web.firewall.RequestRejectedException: The request was rejected because the URL was not normalized.

### Ⅱ. Describe what happened

If there is an exception, please attach the exception trace:

```
Just paste your stack trace here!
```

### Ⅲ. Describe what you expected to happen

### Ⅳ. How to reproduce it (as minimally and precisely as possible)

1. xxx
2. xxx
3. xxx

### Ⅴ. Anything else we need to know?

### Ⅵ. Environment:

- JDK version :1.8
- OS :centos7
- Others:

Start by running the shown nacos-config.sh command against a Nacos 1.3.0 server and inspect the resulting server log for the RequestRejectedException. Trace the script's request construction and compare it with the Nacos endpoint expectations; done means the Seata configuration is accepted without the URL normalization error.
