Updating the default preselection cuts and histrogram ranges

Phase 2 geometry allows taus above |eta|= 2.5. Also, the expected PU is larger than 100. In order to make validation faster (i.e. without re-running on AODs), this PR is changing the default preselection (loosening |eta| cut to 5.0) and extending the histogram ranges in |eta| (to 5.5) and in reconstructed nVx (to 200).

No change in physics expected (only validation sequence affected)
Probably increase in CPU time (more candidates and larger histograms)
