PyTorch Tutorial Audit - ONNX

[sekyondaMeta]

This issue is created because the following tutorials have been marked as containing mentions of/using one of the outdated PyTorch technologies:

https://github.com/pytorch/tutorials/blob/main/beginner_source/onnx/intro_onnx.py
https://github.com/pytorch/tutorials/blob/main/beginner_source/onnx/export_simple_model_to_onnx_tutorial.py
https://github.com/pytorch/tutorials/blob/main/advanced_source/super_resolution_with_onnxruntime.py

Follow this checklist to address the issues in this tutorial:

• If tutorial is irrelevant, delete it and ignore below checkboxes
• Tutorial runs without errors:
  • in Google Colab or appropriate hardware
  • as a Python script.
• Verify that none of the following outdated technologies are present in this tutorial:
  • FSDP1
  • TorchScript
  • Torchserve
  • FX tracing
  • Old TorchMobile (all should reference ExecuTorch)
• The tutorial does not reference old versions of PyTorch except to reference the minimum required version and is free of phrases like "In PyTorch 1.8".
• The outputs of the tutorials do not contain deprecation warnings.
• The tutorial clearly states the prerequisites including the PyTorch version, OS platform, and any special hardware needed.
• The tutorial follows the template.
• All CI checks pass
• Add the tutorials_audit label to the PR

If we don't see a pull request by July 31, we will start deprecating the above mentioned tutorials.
