Storefront API Cart now supports applying Gift Cards

As of version 2024-07 of the GraphQL Storefront API, Cart supports adding and querying for Gift Cards.

Updating Gift Cards can be achieved in two ways:

• When creating a cart - adding the CartInput giftCardCodes property.
• After a cart is created - performing the cartUpdateGiftCardCodes mutation.

You can also query the cart for applied Gift Cards using the appliedGiftCards property.
