Rely on installation of PyGriffin to Workbench 5.0.0 space for CI
This simply removes the reliance on adding a path in my workspace to the CI PYTHOPATH
and relies on an installation of PyGriffin to the Workbench 5.0.0 conda environment on the NSE clusters.
For future reference, the command used to install PyGriffin was:
# executed from the top of the PyGriffin repository
/software/Workbench/Workbench-5.0.0/Workbench-5.0.0/rte/entry.sh -m pip install .
