Docs: inconsistency in `wp_tag_cloud` DocBlock concerning `$number` default value

[audrasjb]

In wp_tag_cloud(), we have the following documentation:

 *     @type int    $number    The number of tags to display. Accepts any positive integer
 *                             or zero to return all. Default 0 (all tags).

But here are the default values for $args:

	$defaults = array(
		'smallest'   => 8,
		'largest'    => 22,
		'unit'       => 'pt',
		'number'     => 45,
		'format'     => 'flat',
		'separator'  => "\n",
		'orderby'    => 'name',
		'order'      => 'ASC',
		'exclude'    => '',
		'include'    => '',
		'link'       => 'view',
		'taxonomy'   => 'post_tag',
		'post_type'  => '',
		'echo'       => true,
		'show_count' => 0,
	);

We should update the DocBlock accordingly to the real default value.
