Feature request: Add a description field to DraftOrderAllDeliveryOptions query

Right now, description is not available for availableShippingRates, many third-party apps use it to show acknowledging details like estimated delivery dates or custom messages.

It would also be really helpful ifavailableLocalDeliveryRates could include the zone name too, since some merchants rely on that to better identify and organize their operations.

These additions would make DraftOrderAllDeliveryOptions much more flexible for different use cases.

      query DraftOrderAllDeliveryOptions($input: DraftOrderAvailableDeliveryOptionsInput!) {
        draftOrderAvailableDeliveryOptions(input: $input) {
          availableLocalDeliveryRates {
            title
            code
            source
            price {
              amount
              currencyCode
            }
          }
          availableLocalPickupOptions {
            title
            distanceFromBuyer {
              unit
              value
            }
            instructions
            source
          }
          availableShippingRates {
            title
            code
            description
            source
            price {
              amount
              currencyCode
            }
          }
        }
      }
