Is your feature request related to a problem?

• No.

Describe the feature you would like.

• I personally prefer to separate the ShardingSphere Agent startup documentation from the ShardingSphere JDBC observability section, as the Agent's documentation is buried quite deep, located at https://shardingsphere.apache.org/document/current/en/user-manual/shardingsphere-jdbc/observability/ .

• 

• I personally believe that the Agent documentation should be at the same level as the JDBC documentation.

@manasagar Hi, I was wondering if you're still working on the current issue? I personally prefer to address the current issue before working on #37723 .

In theory, you can use https://translate.google.com/ to complete the initial translation. A more refined translation can be done through pull requests from other developers. The translated text doesn't need to be accurate; you just need to know that the corresponding text exists in the relevant places. Of course, https://translate.google.com/ doesn't quite understand how to translate code blocks in Markdown, so manual adjustments are required.

If you are using an IDE such as VS Code or IntelliJ IDEA, the IDE's plugin marketplace should also have some jetbrains or third-party Chinese grammar checker plugins.

Will try to get it done as early as possible
