shippingLine.discountedPriceSet now includes cart level discounts

As of version 2024-07 in the GraphQL Admin API, the discountedPriceSet and discountedPrice fields of the object ShippingLine will include cart level discounts applied to an order, including the free shipping discount, when calculating the discounted price. Previously, you would have had to subtract the discountAllocations from discountedPriceSet or discountedPrice to get an accurate value, but doing so now will subtract the same discount twice.
