Easyjet #50: bugfix easyjet ntupler not found grid jobs

• Addresses bug in grid jobs where tarball is not created properly
• Update dataset for mc21 ttbar, dijets, ggF and data22
• Add --dry-run flag to easyjet-ntupler that check arguments are valid and print config to console (together with log level info ie -l INFO --dry-run)
• Rename easyjet-ntupler arguments to kebab case to differentiate them from Athena args (camel case)
• Rename easyjet-gridsubmit arguments to kebab case to differentiate them from Athena args (camel case)
