wrong names and process names for hhtobbvv samples

[nprouvost]

All HH->bbVV samples are marked as HH->bbWW samples, this impacts the cross section and should be changed. Example:

cpn.add_dataset(
    name="ggHH_kl_1_kt_1_hbbhww_powheg",
    id=14857512,
    processes=[procs.ggHH_kl_1_kt_1_hbbhww],
    keys=[
        "/GluGlutoHHto2B2V_kl-1p00_kt-1p00_c2-0p00_TuneCP5_13p6TeV_powheg-pythia8/Run3Summer22EENanoAODv12-130X_mcRun3_2022_realistic_postEE_v6-v3/NANOAODSIM",  # noqa
    ],
    n_files=40,
    n_events=769320,
) 

According to fragment for this sample: https://cms-pdmv-prod.web.cern.ch/mcm/public/restapi/requests/get_fragment/HIG-Run3Summer22EEwmLHEGS-00271/0 the decay H->ZZ is included, this should therefore be included in the name and process
