Java with Ant - JUnit Bug

### Apache NetBeans version

Apache NetBeans 23

### What happened

I created a simple unit test, but it generates the following error when running the test:

/home/ajvelez/.cache/netbeans/23/executor-snippets/junit.xml:184: The following error occurred while executing this line:
/home/ajvelez/.cache/netbeans/23/executor-snippets/junit.xml:128: The or for must include junit.jar if not in Ant's own classpath

### Language / Project Type / NetBeans Component

Java / Java with Ant / JUnit execute

### How to reproduce

Create a Java with Ant y execute the next test

```java
public class NewEmptyJUnitTest {

public NewEmptyJUnitTest() { }

@Test
public void hello() {
assertEquals(20, 20);
}
}
```

### Did this work correctly in an earlier version?

No / Don't know

### Operating System

Fedora 40

### JDK

JDK17 and JDK22

### Apache NetBeans packaging

Apache NetBeans provided installer

### Anything else

_No response_

### Are you willing to submit a pull request?

No

Reproduce the Java with Ant JUnit test in Apache NetBeans 23 using JDK 17 or 22 and Fedora 40. Inspect the generated executor-snippets/junit.xml references at lines 128 and 184; done means the sample test runs without the missing junit.jar classpath or modulepath error.
