In an MR project quick fix updates the wrong module-info.java

In an MR project with module-info.java per release folder src, src17, src24:
* in a class in src24 add a reference to a not-accessible jdk class.
* invoke quick fix "Add 'requires java.foo' in module-info.java"

This statement will be added in `src/module-info.java` while probably it should be added in `src24/module-info.java`.

This issue probably needs a change in jdt.ui, but let's first check if jdt.core provides all necessary information.

Reproduce the quick fix in an MR project using src, src17, and src24, with the inaccessible reference in a class under src24. Trace the "Add 'requires java.foo' in module-info.java" entry point through jdt.core and the likely jdt.ui change, checking whether core exposes the relevant module information. Done means the requires statement targets src24/module-info.java rather than src/module-info.java.
