B-physics trigger: add low pT tag-and-probe bJpsimutrk chain (ATR-23155)
This MR adds 'HLT_mu6_bJpsimutrk_lowpt_MuonTrkPEB_L1MU5VF'. Additional track which has to be paired with reconstructed muon should have pT > 2GeV (the default value is 3GeV).
The number of created features xAOD::TrigBphys created by BmutrkEFComboHypo algorithm should increase (since we change trackPtThresholds value), but the final number of the already implemented MuonTrkPEB chains should remain the same.
