Fix SMOG2 unstable physics efficiency test

Fix of the bugged invariant-mass evaluation in the D2Kpi SMOG2 selection, which was leading to unstable results in the efficiency_full ci step.

Some ci data tags are also updated to the _v1 retina cluster version

Tested with pipeline 4009286. Failures only found to be related to M100 and unrelated to this MR

Thanks for this. This is very important as it removes the unstable behaviour in the CI of Allen. Let's run a Jenkins CI test and merge if that passes:

/ci-test
