Fixed visibility issue for all notebooks on GitHub

[Archit-Kohli]

Description

This pull request just changes the inner JSON format of all run.ipynb files in gradio/demo/ and makes the cell ids strings, thus making it a valid notebook which can now be seen in GitHub itself

Closes: #5916

Please merge my pull request and if possible add the hacktoberfest label

@Archit-Kohli Thanks for taking care of this!

We also need to update the python file that generates the notebooks to make sure we don't reintroduce this problem. It is in demo/generate_notebooks.py. Could you update that as well?
