Interoperability test suite preview with SCITT API Emulator using Postman

Long term goal: https://w3c-ccg.github.io/traceability-interop/reports/interoperability/

[OR13]

• Add a postman collection that can be run with newman that covers a single endpoint with tests.
• Wire the reporter / renderer to CI, so the report is published

Don't worry about multivendor, focus only on conformance for the emulator first.
