Thank you for your ongoing contribution to enhance ONNX support!

I think overall looks good. However, this PR raises yet another issue with input shapes (discussed here previously: #2304 (comment)). In short, Burn tracks shapes dynamically but ONNX allows for static and dynamic shapes - we should get away from static shapes.

I am approving this PR with a condition that you file a new issue to enhance RandomLike that would figure out shapes dynamically. You can link and update this description to say it only handles static input shapes. And the other issue will refactor it. It will contain two action items: enhance Burn's tensor method with new random_like method and update this burn-import.
