#1234 - Update Swagger for callback create route require property notification statues

[MackHalliday]

Description

issue #1234

We are updating the Swagger documentation for POST /service/{service_id}/callback. Originally, the documentation said the field notification_statuses was required if the callback_type is delivery_status. However, this is not true. If notification_statuses is not included, the service by default will receive updates on ALL notification_statues. I have updated the Swagger doc to reflect how the endpoint actually behaves.

How Has This Been Tested?

• Deploy to DEV OK
• Open Swagger docs in Swagger Edit
