The documentation needs to add instructions for the `apache/seata-naming-server` Docker Image

### Check Ahead

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

- [ ] I am willing to try to implement this feature myself.

### Why you need it?

- The documentation needs to add instructions for the `apache/seata-naming-server` Docker Image.
- I saw that https://hub.docker.com/r/apache/seata-naming-server has uploaded the Docker Image of Seata Naming Server 2.4.0. However, it lacks self-description text, and https://seata.apache.org/zh-cn/docs/user/registry/namingserver does not mention how to configure this Docker Image, which brings inconvenience.

### How it could be?

- Add instructions for the `apache/seata-naming-server` Docker Image.

### Other related information

- No.
