TrigGlobalEfficiencyCorrectionTool: raising photon trigger thresholds to recommended values

For photon triggers, in general trigger scale factors should be applied only to photons with pT > HLT threshold + 5 GeV. But the TrigGlobalEfficiencyCorrectionTool currently uses a default of HLT + 1 GeV as for electrons. Thanks Christos for the reminder. This MR updates the configuration file (and two examples) to fix that.

Expected impact: if offline selection/trigger matching was done with the proper thresholds, only events with more offline photons than required at trigger + at least one of them in the critical interval (HLT+ 1GeV to 5 GeV) would have received a SF slightly different than what it should have been, but likely by a quite small amount.
