• Bulk Export cancellation behavior update by @apurvabhaleMS in https://github.com/microsoft/fhir-server/pull/5388

Added updates to align the FHIR server to support Bulk Data Access 2.0. This includes a change to bulk export cancellation behavior. Previously, cancellation request of an already completed, cancelled, or failed export job returned "200 OK". The behavior is now updated to return more informative operation outcomes:

• Cancelling an already-cancelled export job returns "404 Job Not Found"
• Cancelling a completed or failed export job returns "404 Job Not Found" if the job has already cancelled or failed; otherwise return "202 Accepted"
• Cancelling a queued or running export job returns "202 Accepted", no behavior change.
• Trying to get the status of a user-requested cancelled job returns "404 Job Not Found"
