block_core_breadcrumbs_create_item: add cond. return type

[IanDelMar]

block_core_breadcrumbs_create_item():

 * @param string $text       The text content.
 * @param bool   $is_paged   Whether we're on a paginated view.
 *
 * @return array The breadcrumb item data.
 */
function block_core_breadcrumbs_create_item( $text, $is_paged = false ) {
	$item = array( 'label' => $text );
	if ( $is_paged ) {
		$item['url'] = get_pagenum_link( 1 );
	}
	return $item;
}

block_core_breadcrumbs_create_item() returns an array with $text as is keyed by 'label' (template T). If $is_paged is truthy a key 'url' with string value is added (conditional return type).
