I found the solution for you; you just need to updated the TAG function (wp_tag_cloud) located in category-template.php:
* just replace (‘number’ => 45) to whatever you like or to 0 value for unlimited number of tags

function wp_tag_cloud( $args = '' ) {
	$defaults = array(
		'smallest' => 8, 'largest' => 22, 'unit' => 'pt', 'number' => 45,
		'format' => 'flat', 'orderby' => 'name', 'order' => 'ASC',
		'exclude' => '', 'include' => ''
	);

And check my website I reset the number to 100:
