No longer add the Felix SCR annotations to the list of dependencies

To encourage more modules to switch to OSGi 6 annotations, we should not only mark the dependency with the (invisible) comment DEPRECATED (as being done with SLING-5857), but instead no longer put that dependency by default into the classpath. Just having that in the dependencyManagement is enough, so that for new modules already leveraging only the new annotations the classpath is no longer polluted by this unnecessary class.
