External Ids for Fulfillment Order Holds

As of 2023-01, you can tag fulfillment order holds with an external ID.

This can be used to track states within your own application on why a fulfillment order has been placed on hold and when it needs to be released. This can be done by utilizing the new FulfillmentOrderHoldInput.externalId field argument described here.
