[ATR-30593] Avoid using the keywords Primary or TagAndProbe in chain group names in the MC menu
This works around TriggerAPI based parsing of the menu based on Chain Groups, which is a temporary solution used for mid-year data and MC DAOD production, prior to that year's GRL being made available (and a TriggerAPI Session being stored based on this GRL)
With these changes, chains which are added by the MC menu will no longer be considered as potential candidates to be classified as the Lowest Unprescaled Trigger in any considered chain classification.
