Update main-cart-items.liquid

Fixes #0.

What approach did you take?

Since we can use the product object in the item object, I chose to use the product object to get the compare_at_price and the price of the product.

Thanks for this!

@melissaperreault Do you think this is something we would want to include? It might be confusing since it would be similar to how we show discounts.
