Scenario to remove the Pixel extension

This scenario (GeometryExtended2023SHCalNoTaperNoExtPix) is based on GeometryExtended2023SHCalNoTaper but without the extended part of the Pixel - This is not a scenario supposed to be maintained in the future (not a baseline) but just to have a scenario for which no tracks beyond ~2.4 are reconstructed as requested for further studies intended for the Technical Proposal
The lifetime of this scenario is therefore linked to the Technical Proposal
The WF numbers are 134xx
