Add z-integrated tomography line to default physics sequence
Following the request of the pit crew, this MR adds the z-integrated tomography line to the default pp sequence, as a temporary solution while the work ongoing in !1192 (merged) is completed.
Rate tested on 2023 open VELO simulation is Eff=|(0.2100000 +- 0.0457776)%|
and I checked reconstructed material vertices are as expected
