Fix generics used within addObserverMethod

cdiEventEndpoints.values().stream().forEach(endpoint -> abd.addObserverMethod()
    .beanClass(CdiEventComponent.class)
    .observedType(endpoint.getType())
    .qualifiers(endpoint.getQualifiers())
    .notifyWith(endpoint::notify);

cdiEventEndpoints.values().stream().forEach(endpoint -> addCdiEventObserver(abd, endpoint));

private <T> void addCdiEventObserver(AfterBeanDiscovery abd, CdiEventEndpoint<T> endpoint) {
    abd.<T>addObserverMethod()
        .beanClass(CdiEventComponent.class)
        .observedType(endpoint.getType())
        .qualifiers(endpoint.getQualifiers())
        .notifyWith(endpoint::notify);
}
