Enable quick add button

The "quick add" button allows customers to add a product to their cart from the product card. If the product has variants, then the button reads Choose options and displays the product details in a pop-up. The customers can then select their desired variants, add to cart, check out immediately with the Buy it now option, or else click to view a product's full details. The Buy it now option needs to be set up separately from the product page to appear in the quick add options. When the Buy it now option isn't set up, customers can still add the product to their cart.
