EgammaCalibrationConfig: Do not hardwire output-level
While testing something else, I came across the following spurious DEBUG messages:
10:47:42 2023-01-23 10:47:17,698 T2CaloEgamma_Ringer.EgammaHitsCalibrationEndcap DEBUG Calling destructor
10:47:42 2023-01-23 10:47:17,698 T2CaloEgamma_Ringer.EgammaTransitionRegionsConfig DEBUG Calling destructor
10:47:42 2023-01-23 10:47:17,698 T2CaloEgamma_Ringer.EgammaHitsCalibrationBarrel DEBUG Calling destructor
I found that EgammaCalibrationConfig forces the OutputLevel to 0. This MR removes these lines.
