The Null Annotations jar: org.eclipse.jdt.annotation does not have a module-info.java

The Eclipse nullable annotations jar does not have a `module-info.java` which makes using `jlink` extremely difficult.

The simplest solution is to use something like moditect or a multi release jar.

Without this I will most likely have to switch to JSpecify jars sooner as they have a `module-info.java`.

@stephan-herrmann I'm happy to try to put in a PR however I'm not as familiar with the `tycho-compiler` and not sure what its compatibility is with something like moditect.
