PR description:
This PR adds a vertex smearing for 2022 PbPb MC.
The vertex positions use the beamspot in 2022 PbPb data along with the BPIX barycentre provided by Tracker Alignment group. Details see CMS-Talk. The width parameters (sigmaZ) are taken from 2022 PbPb, which is quite close to what we got in 2018.
