Test is failing with small diffs in some counters for PrStoreSciFiHits

Otherwise, test runs fine and is using latest LHCBGAUSS-2635 sample needed for dd4hep compatibility.

Not 100% sure why we didn't just provide the dd4hep ref for this with !2531 (merged) ?

Can we just provide the dd4hep specific refs here ?
