Update IDPVM ART Z' test to use same memory core config as other reco jobs (!74862) · Merge requests · atlas / athena · GitLab

Uses same config as for instance https://gitlab.cern.ch/atlas/athena/-/blob/24.0/InnerDetector/InDetValidation/InDetPhysValMonitoring/test/test_mu20GeV_reco.sh?ref_type=heads#L6

Hopefully improves the success rate of this test
