Jet Trigger test chains for Run 3 baseline menu changes (ATR-24720)

Adding jet trigger test chains to Dev_pp_run3_v1 for study for suggested changes to Run 3 baseline menu. 2 studies:

1. Add several single forward jet triggers to evaluate rate following @sschramm's suggestion that we lower the lowest unprescaled forward jet trigger threshold as it currently runs at a lower rate than the support chains
2. Add several HT1000_L1HT190-J15s5pETA21 variations with different preselections, mostly of type multijet.

Tagging @khoo , @ayana . Putting this up for comment, can finalise in the new year.

Trigger counts in reference files have been updated.
