AthenaMonitoring DQConfigFlags: Disable HLT mon for data AOD input (ATR-28781)

Adjusting Athena monitoring DQ steering so that DQ.Steering.doHLTMon = True only if DQ.Environment != 'AOD'(if input file is not AOD) for Run 3. This is in preparation for the removal of sizeable HLT containers from AOD for significant storage savings, !70041 (merged). This will break any HLT monitoring running on AOD. We therefore aim to limit future workflows to running HLT monitoring only on RAW input data.
