New reason and lineItems fields for rejecting fulfillment requests

As of GraphQL Storefront API version 2022-07, the fulfillmentOrderRejectFulfillmentRequest mutation has two new optional arguments:

• reason: Identify the reason the fulfillment request was declined. It can be used to filter, group, and provide workflows to help merchants solve rejection issues.
• lineItems: Identify which line items in a fulfillment request are causing the rejection, and provide a detailed message for each one.

Also in this version, the FulfillmentOrderLineItem object has a new generic warnings field, which can be used to display rejection issues for the line item.
