Allow org.eclipse.jdt.junit.core access to internal methods

[trancexpress]

To distinguish between JUnit 5 and JUnit 6 annotations when launching tests, we potentially look into manifests.

In order to use PackageFragmentRoot.getManifest() to this end, org.eclipse.jdt.junit.core is now in the friends list of package org.eclipse.jdt.internal.core.

Fixes #4663
