RFR: 2254: TestInfoBotWorkItem should handle Runtime Exception

[Zhao Song]

I created a PR in SKARA(https://github.com/openjdk/skara/pull/1647) and I found the GitHub actions are in the running state for more than about 2 hours. But actually, the GitHub actions are finished(https://github.com/zhaosongzs/skara/actions/runs/8990857032/job/24697152747). From the log, I could see TestInfoBotWorkItem got 500 error when querying the checks for this pr. However, TestInfoBotWorkItem wasn't retried. After investigation, I found TestInfoBotWorkItem doesn't handleRuntimeException.
