Fix test_egamma_run_data.sh ESD checks (!21700) · Merge requests · atlas / athena

NOTE: This MR branches off of !21313 (merged)

It adds one extra commit: 6e6399b2

This is to follow up ATR-19507

I suggest this is merged immediately following on from !21313 (merged) as the extra changes on top are trivial.
