Use groups labels consistently, from LbAPCommon
Follow-up comment from LbAPWeb#12 (closed):
the group labels are displayed lowercase in the web app but it would seem nicer and more consistent to use the same ones (e.g. B2OC
rather than b2oc
) everywhere in the AProds frameworks, see the known list at https://gitlab.cern.ch/lhcb-dpa/analysis-productions/lbapcommon/-/blob/master/src/LbAPCommon/config.py#L12-33.
