GitHub cannot render going_modular notebooks due to outdated widget metadata

[pranav-mahure]

Hi Daniel,

Thanks for maintaining this repository and creating the PyTorch course.

I noticed that GitHub is currently unable to render some notebooks in the going_modular section. GitHub shows the following error:

There was an error rendering your Notebook: the 'state' key is missing from 'metadata.widgets'. Add 'state' to each, or remove 'metadata.widgets'.

The affected notebooks are:

• 05_pytorch_going_modular_cell_mode.ipynb
• 05_pytorch_going_modular_script_mode.ipynb

After investigating, it appears the issue is caused by outdated widget metadata that is no longer compatible with GitHub's notebook renderer.

Removing the metadata.widgets section allows the notebooks to render correctly while preserving their contents.

I've opened a pull request with the proposed fix.

Thank you for your work on this project.
