source.generate.finalModifiers should not add final modifiers to the fields

If I have a field line that:

class User {
    @Parameter(names = { "--age", "-a" }, required = true, description = "User age")
    public int age = 1;
}

following option:

    "[java]": {
        "editor.codeActionsOnSave": {
            "source.generate.finalModifiers": true
        }
    }

add final modifier to it:

class User {
    @Parameter(names = { "--age", "-a" }, required = true, description = "User age")
    public final int age = 1;
}

but it should not, because it can be changes from other code or library like JCommander.

Environment

• Operating System: macOS Sonoma 14.0
• JDK version: Zulu 8.72.0.17-CA-macos-aarch64
• Visual Studio Code version: 1.82.2
• Java extension version: 0.25.14

首先在 vscode-java 代码库中找到 source.generate.finalModifiers 的实现和测试。使用一个带注解且可变的 Java 字段（如 issue 中的 User.age 示例）复现该行为，然后添加回归测试，表明当该字段可能被外部修改时，该设置不会添加 final。
