calls to /auto/runinfo are returning Timestamp and Type keys

[chriswhong]

Run -> RunStep.output should be EventLogLine

export interface EventLogLine {
  type: EventLogLineType
  ts: number
  sessionID: string
  data: Record<string, any>
}

Calls to /auto/runinfo are returning steps where output has keys Timestamp and Type with capitalized letters. Need to make it match the expected interface.
