Add Hlt2 settings for max candidates combiner test

This Moore file is a copy of hlt2_pp_2024.py with an extra function that creates a json file with a mapping between algorithms and lines. This is used in the Max candidates test to add line names to the algorithms that trigger the "Too many candidates/combinations" warnings. This is detailed in this merge request: lhcb-datapkg/PRConfig!436 (merged).
