Draft: Fix for extrapolated chargedPFO - neutralPFO association in TauRec

During the tau reconstruction, a step consists of associating the extrapolated chargedPFO to the closest neutralPFO within dR<0.04.

This MR is fixing the neutral PFO four-momentum used for the dR calculation, using the vertex corrected four-momentum which is associated to the neutral PFO in https://gitlab.cern.ch/atlas/athena/-/blob/main/Reconstruction/tauRecTools/src/TauPi0ClusterCreator.cxx?ref_type=heads#L72

` // -- Set the PFO four momentum corrected w.r.t. the tau vertex

neutralPFO->setP4(clusterP4.Pt(), clusterP4.Eta(), clusterP4.Phi(), 0.);

`

instead of the non-corrected four-momentum directly retrieved from the cluster.

Changes in output are expected
