ACF Nav Menu Plugin Support

This adds support (native) for the ACF Nav Menu field plugin (https://github.com/jgraup/advanced-custom-fields-nav-menu-field). This also requires WPGraphQL for Advanced Custom Fields.

add_filter( 'wpgraphql_acf_register_graphql_field', function( $field_config, $type_name, $field_name, $config ) {
	if ( isset( $config['acf_field']['type'] ) && 'nav_menu' === $config['acf_field']['type'] ) {
		$field_config['type'] = 'Menu';
		$field_config['resolve'] = function( $root, $args, \WPGraphQL\AppContext $context, $info ) use ( $config ) {
			$menu_id = get_field( $config['acf_field']['key'], $root->databaseId );
			return ! empty( $menu_id ) ? $context->get_loader( 'term' )->load_deferred( $menu_id ) : null;
		};
	}
  return $field_config;
}, 10, 4 );
