fixed bit assignement in the MC inputs file
Recently the Trigger Validation shifter observed a count jump in
L1_DPHI-M70-2eEM12M, https://test-atrvshft.web.cern.ch/test-atrvshft/ART_monitor/CountChecker/2024-11-26/main_Athena_x86_64-el9-gcc13-opt/trig_mc_v1Dev_slice_egamma_grid
A recent MR !76073 (merged) which went into 24.0 about a week ago was merged into main before this nightly. I believe my !MR76073 somehow interacted with a bug already present in the MC inputs file, where bits already in use in the Physics inputs file have been re-assigned.
