[ONNX] Add comment on test_view_dynamic_zero_dim (#105950)
From https://github.com/pytorch/pytorch/issues/105066.
The case was meant to test 0 bbox generated by vision models, but the bboxes still have `.view()` operated. The case was disabled, and not supported. Added a comment to clear the potential confusion in the future. We will wait for model example to proceed on this.
