cmssw: [GPU] Workflow failures when running the alpaka customization in presence of a `Fake` menu

Several workflows {12434,12450}.{402,403,404,412} fail in GPU IB tests in CMSSW_14_1_GPU_X_2024-02-26-2300 along:

DIGI:pdigi_valid,L1,DIGI2RAW,HLT:@relval2023,ENDJOB
We have determined that this is simulation (if not, rerun cmsDriver.py with --data)

this likely comes from the integration of https://github.com/cms-sw/cmssw/pull/44026 that moved @relval2023 to @Fake2.
