Test runner needs correctly formatted output from TesterMain

see https://github.com/exercism/docs/blob/main/building/tooling/test-runners/interface.md

{
  "version": 2,
  "status": "fail",
  "message": null,
  "tests": [
    {
      "name": "Test that the thing works",
      "status": "fail",
      "message": "Expected 42 but got 123123",
      "output": "Debugging information output by the user",
      "test_code": "assert_equal 42, answerToTheUltimateQuestion()"
    }
  ]
}

Current output missing "message" and "test_code" items.

     { "name"  : "Test 23: non-question ending with whitespace",
       "status": "fail" }
   ],
   "version": 2,
   "status": "fail"
 }
