Adding pT cut for b-tagging selection tool, Open up selection in tagging tool

This MR adds the MinPt criteria to the initialization of the BTaggingSelectionTool that was introduced in 31061. This should fix the problems observed in TOPQ4 and JETM7.

Furthermore after discussing with FTAG experts, it was decided to remove a pT criteria for the tagging decision in case people apply this to VR track-jets (instead of R = 0.4 jets). Open up the eta cut from 2.5 to 2.7.
