Display attribute description instead of name in tooltip

Hi @hogo

Please update our plugin to the latest version 1.0.8 then add below snippet (How to add snippet?):

add_filter( 'wpclv_term_label', 'your_wpclv_term_label', 99, 3 );
function your_wpclv_term_label( $label, $term, $product_id ) {
	if ( ! empty( $term->description ) ) {
		return $term->description;
	}

	return $label;
}

Thanks, It cause a 500 error by i removed the product id from function parameters and it worked.
