No completion for args parameter of NI launch configuration in VSCode

### Apache NetBeans version

Apache NetBeans 21

### What happened

I am trying to debug my native executable in VSCode extension and I am trying to **pass arguments** to the executable. There is no code completion on the `args` parameter.

### Language / Project Type / NetBeans Component

Native Image

### How to reproduce


It is really hard to even find there is the `args` parameter. I was lucky to guess it. Please add proper _code completion_ support for the `args` argument in the launch configuration, @entlicher.

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

No / Don't know

### Operating System

Ubuntu

### JDK

GraalVM 21.0.2 Community

### Apache NetBeans packaging

Apache VSNetBeans for VSCode

### Anything else

.

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

Yes

Start by locating the launch configuration completion handling in the Apache VSNetBeans extension and compare it with completion for the other launch parameters. Add completion for the `args` parameter and verify that it is suggested when editing a Native Image launch configuration in VSCode.
