I think that this change is simple enough that it can be merged and a cmsdist PR can be made so that we can check this in jenkins in connection with the cms-sw/cmssw#23768

@hqucms , we are now using mxnet 1.5.0 in CMSSW_11_0_X. Can you please update these json files for the new version to avoid the warnings [a]?
