TrigEgammaMonitorPhotonAlgorithm: add ReadDecorHandleKey to retrieve offline photon isolation
Hello,
As discussed in ATR-26212 and ATR-26052, the HLT offline monitoring retrieves offline photon isolation decorations before they are created. This MR implements a ReadDecorHandleKey such that the monitoring reads the decorations only after they are created.
