New field deliveryGroups for the cart object

As of GraphQL Admin API version 2022-04, a new deliveryGroups connection has been added to cart. It consists of a group of delivery options available for the line items in the cart, for a specified shipping address. Delivery groups are only available for logged-in customers with a full default address.

Refer to our documentation on cartCreate and customerCreate to learn more about how to create a cart associated with a logged-in customer.
