[PSM Interop] Fixes the triager hint - add missing date, turn off the highlighter (#34030)

Addresses some issues of the initial triage hint PR:
https://github.com/grpc/grpc/pull/33898.

1. Print unhealthy backend name before the health info - previously it
was unclear health status of which backend is dumped
2. Add missing `retry_err.add_note(note)` calls
3. Turn off the highlighter in triager hints, which isn't rendered
properly in the stack trace saved to junit.xml
