updating mc23a profile for new luminosity calibration
The new luminosity calibration is 5% lower, resulting in a corresponding shift in the target mu distribution. This merge request updates the multiple and single beamspot profiles for mc23a in legacy and CA configuration.
I had to shift the profile for the three levelling periods by 7 instead of 5 units from mc21a, otherwise they exceed the value of the target distribution at high mu. I missed that in the first commit, fixed by the push at 12.17 pm. As before the post-level distribution is the different between the target distribution and the sum of those in the first three leveling periods.
