first version of alignment parameters for the May 2024 Ni-Ni data

First version of the alignment for the mcbm_beam_2024_05_08_nickel setup.

• Should be used/called from the steering macro https://git.cbm.gsi.de/computing/cbmroot/-/blob/master/macro/beamtime/mcbm2024/mcbm_event_reco_L1.C
• Preferably one should also reduce CA search windows and/or release the target bias according to the model:
