Adding gridpack for existing jO 525956 [skip modfiles]
- Gridpack is added to existing jO 525956 (aMCPy8EG_tWZ_Ztoll_DR2) because without it the jobs for DR2 samples keep crashing due long run time: ProdTask link
- This sample is requested in the JIRA ticket: ATLMCPROD-10911
- The jO is changed only to use the added Gridpack
