Powheg: Fix again, HH_SMEFT, and HH, due to authors' python code changes - AGENE-2315
requested to merge atlas-physics/pmg/mcexperts/powheg-experts/athena:Powheg_another23.6.41Fix into main
Fixes in two Powheg processes
- Fixing again HH_SMEFT for bug reported in AGENE-2315 - this time for the case
PowhegConfig.usesmeft = 0
- Also, fixing a bug in HH; need to keep the path to lhapdf installation in $PYTHONPATH because the Powheg process seems to re-use the python script which includes it (which is certainly pointless but we can't change this in the authors' code)
In both cases this is due to changes in the python scripts in these Powheg processes
