Fix bug in defining bin edges of TH2F plots in ECAL DQM

[abhih1]

PR description:

This PR fixes a bug that crept in PR #42188 in here [1] which was giving nonphysical values to the bin edges of certain TH2F plots [2] [3] in the Ecal DQM, due to which they were not being filled correctly ever since central DQM switched to CMSSW_13_2_2 from CMSSW_13_0_10.
