Run3 crosssections

[danielwinterbottom]

• Adding cross sections for Run-3
• Samples that are not currently available are commented out
• For Run-3 we will do the kfactor scaling inside the cross sections file
• The kfactor scaling is thus removed in the stitching. It needs to be check that this works properly and also does not break anything when processing Run-2
• The dataset names are also updated but need to modify the code to account for 2022_preEE havign 2 dataset names: SingleMuonC, MuonC, and MuonD
