As part of internal services migration of XSC into Xray - the field fail_build wasn't returning in the response from Xray - and didn't fail the run - even if it did create a violation according to the defined policies.

The fix itself happened on Xray v3.111 - and we wanted to add a test for audit to run against it as well in JFrog-CLI
