Update dijet+X chains to use DJMASS aliases
As discussed in ATR-23404, the following MR updates the name of dijet+X chains to start using the new naming convention for DIJET scenario aliases.
The behaviour of the following chain has changed since the incorrect pt selections to the dijet hypo were used (70 instead of 50)
