ATLASRECTS-7583: Ignore more ONNXRuntime warnings

A lot of the onnx models that flavor tagging has uploaded have been semi-broken: they should keep running and producing the correct outputs but they have defects that are serious enough that ONNXRuntime feels the need to comment via log.

I suspect we're not being careful enough to clean these models up before the upload. Unfortunately they are already in use now, so the best we can do is turn off the warning messages.
