Draft: Fixing chains of type HLT_j120_afprec_afpdijet ATR-24206

Fixing chains that required a single jet plus afp track reco plus afp dijet combo hypo. Afp dijet combo hypo needs at least two jets, error reported here ATR-24206. Tried adding an asymmetric jet threshold and ran into problems with menu alignment, as discussed in JIRA. Changing chains to require 2j with same threshold, for example:

HLT_j120_mb_afprec_afpdijet ---> HLT_2j120_mb_afprec_afpdijet

Does not explain problem with asymmetric thresholds but for now these chains are ok, since we anyway need both jets to have a high-pt to ensure that both protons are within AFP acceptance
