New args for apply_filters in WP_Widget_Archives

[sebastian.pisula]

I suggest add new arguments for Widget. For example I can use archive widget for another post types:

<?php

/**
 * Filter the arguments for the Archives widget.
 *
 * @since 2.8.0
 * @since 4.5.0 Added new params $widget_args, $instance and $widget_archive
 *
 * @see wp_get_archives()
 *
 * @param array $args An array of Archives option arguments.
 * @param array $widget_args Array of arguments including 'before_title', 'after_title',
 *                           'before_widget', and 'after_widget'.
 * @param array $instance Settings for the current Archives widget instance.
 * @param WP_Widget_Archives $widget_archive Object Current Widget
 */

add_filter( 'widget_archives_args', function ( $args, $widget_args, $instance, $widget ) {

        if ( $widget_args['widget_id'] == 'archives-2' ) {
                $args['post_type'] = 'page';
        }

        return $args;
}, 10, 4 );

I know that date archives is not supported for other post type but this is example (but I can make support for other post type :) )
