Unable to suppress TODO diagnostics using java.errors.reportTodoComments or java.errors.suppressedDiagnostics

[meethey]

I'm encountering an issue where TODO comments in Java files are still being reported in the Problems window, even after explicitly disabling them via workspace settings.

Steps to Reproduce:

1. Create a new Java file with a TODO comment:

public class Test {
public static void main(String[] args) {
// TODO: This is a test
System.out.println("Hello");
}
}

2. Add the following to .vscode/settings.json:
   {
   "java.errors.reportTodoComments": false,
   "java.configuration.taskTags": [],
   "java.errors.suppressedDiagnostics": [
   "536871362"
   ]
   }

3. Restart VS Code and optionally run Java: Clean Java Language Server Workspace.

Expected Behavior:
The TODO comment should no longer appear in the Problems window.
Actual Behavior:
The TODO comment is still reported as an informational diagnostic:
TODO: This is a test Java(536871362)
