Add test cases for the PyTorch notebooks

Description

This pull request encompasses the addition of test notebooks for both variants of PyTorch notebooks within the 2023a release. The included test notebooks focus on the evaluation of specific Python packages, as follows:

• torch
• tensorboard
• torchvision

This update aims to enhance the testing and validation process for the mentioned PyTorch notebooks, ensuring their compatibility and functionality within the specified package versions

How Has This Been Tested?

Launch the two distinct variants of PyTorch Jupyter Notebook images, 'ubi8' and 'ubi9'. Then, execute the 'test_notebook.ipynb' file in each respective image, and ensure that all tests pass.

To evaluate the PyTorch ubi9:

podman run -it --rm -p 8888:8888  quay.io/opendatahub/workbench-images:jupyter-pytorch-ubi9-python-3.9-pr-187

To evaluate the PyTorch ubi8:

podman run -it --rm -p 8888:8888  quay.io/opendatahub/workbench-images:jupyter-pytorch-ubi8-python-3.8-pr-187
