Fix Muons configs

[bonanomi]

@Lara813 spotted a bug in the config for muons (for sure in this one), but maybe also in others.

The reference_object should use the [GenPart](https://github.com/cms-l1-dpg/Phase2-L1MenuTools/blob/main/configs/V44nano/objects/GenPart.yaml):object:region definition, as done, eg, in the electron_matching.yaml config.

It should be:

TkMuonsMatchingBarrel:
  sample: DYLL_M50
  version: V44nano
  match_test_to_ref: True
  reference_object:
    GenPart:reference_muon:barrel_muon: "pt"
  test_objects:
    # L1gmtMuon:default:barrel: "pt"
    L1gmtTkMuon:default:barrel: "pt"
    L1gmtTkMuon:VLoose:barrel: "pt"
    L1gmtTkMuon:Loose:barrel: "pt"
    L1gmtTkMuon:Medium:barrel: "pt"
    L1gmtTkMuon:Tight:barrel: "pt"
  xlabel: "Gen. $p_T$ (GeV)"
  ylabel: "Matching Efficiency (barrel)"
  binning:
    min: 0
    max: 100
    step: 3

Also note that for muons in GenPart there are two regions: barrel_muon and endcap_muon that should be used, since also the overlap region should be used for muons.

Also tau, jet and photon configs and exclude 'reference' in object names
