Legacy jet monitoring tool default chain plotting changed for AthenaMT samples
As discussed with @jbossios in this ticket: https://its.cern.ch/jira/browse/ATR-21819
I changed the legacy jet monitoring tool such that when running over AthenaMT input samples, the fillBasicHLTforChain
function fills the default plots for "all jets" of the underlying jet container, while putting the "only jets that pass the chain criteria" into a subfolder chain_name+"/PassingJets"
