Changed breadcrumb match for arrow placeholder from value to key in component/listing/breadcrumb.html.twig and component/product/breadcrumb.html.twig to avoid a missing arrow when the last element has the same name as another.
Added new variable breadcrumbKeys in component/listing/breadcrumb.html.twig
