Demote module deletion printout to INFO

[makortel]

PR description:

#29553 included a WARNING level printout for the modules being deleted to aid debugging of possible problems in IBs. Such problems have not appeared after several days, so I think it is safe to demote the printout to INFO (as anticipated in #29553 (comment))

After #32244 gets merged, the list of deleted modules can be printed with

process.MessageLogger.cerr.threshold = "INFO"
process.MessageLogger.cerr.DeleteModules = dict()

PR validation:

Workflow 25.0 step3 is clean from the printout present in the IB.

This pull request is fully signed and it will be integrated in one of the next master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @silviodonato, @dpiparo, @qliphy (and backports should be raised in the release meeting by the corresponding L2)

@cms-sw/reconstruction-l2 On a cursory look vast majority of "modules deleted because of no consumers" are in RECO+MiniAOD step (things like ak4CaloL1FastL2L3Corrector, elPFIsoValueCharged03NoPFIdPAT, muPFIsoValueCharged03PAT, patPFMetT0pc, pileupJetIdCalculator, tauIsoDepositPFCandidates). Would it be worth of the effort to follow up on these? (I have a copy of full matrix logs from IB, but I won't bother with further processing if there is no interest to follow up the results)
