[VSCode extension] NetBeans gives errors because `java.base` is not read

### Apache NetBeans version

Apache NetBeans 16

### What happened

NetBeans gives errors because my module is said not to read `java.base`, which is odd, because every module reads `java.base` implicitly:


### How to reproduce

I created a new Maven project based on an archetype and added a class to it.

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

No / Don't know

### Operating System

Windows 11

### JDK

openjdk full version "20-ea+22-1594"

### Apache NetBeans packaging

Apache VSNetBeans for VSCode

### Anything else

_No response_

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

Yes

### Code of Conduct

Yes

Reproduce the report with Apache NetBeans 16, the Apache VSNetBeans for VSCode extension, a Maven project from an archetype, and the supplied OpenJDK 20 early-access version. Investigate why the new class is reported as not reading java.base; done means the erroneous diagnostic no longer appears for a module that implicitly reads java.base.
