Feature suggestion: Show warning when javadoc doesn't match the method signature and offer a code action to update it

It’s difficult to remember to update the Javadoc of a method after modifying its signature. It would be practical if the extension could detect this mismatch, show a warning, and propose an update.

Environment

• JDK version: 17
• Visual Studio Code version: v0.29.0
• Java extension version: 1.93.1

Steps To Reproduce

1. Generate a java doc for a method
2. Add a new argument to the method

Current Result

An outdated javadoc

Expected Result

1. Show a warring
2. Execute a code action to update the javadoc
3. An updated javadoc

未确定文件、测试或入口点。首先使用 JDK 17、VS Code 0.29.0 和 Java extension 1.93.1 重现不匹配，然后定位 extension 的 diagnostic 和 code-action 入口点。当签名不匹配产生警告和一个更新 Javadoc 的 action 时，即视为完成。
