Cart: Invert the X close icon color

If you've customized your modal cart to be a dark color, the close X icon will not be visible. This code change will invert the color to allow it to show on a dark background:

Code:

/* -- code to invert modal cart close icon -- */
.ajaxcart__close { filter: invert(100%) !important; }
/* - end - */
