Find out how to render text heat maps in GitHub preview

[aaarrti]

From top to down the views generated by:

• PyCharm
• Colab
• JupyterLab
• GitHub preview

Ideally, we want them all to be rendered in the same view. I think this could be caused by GitHub preview treating Jupyter notebook as HTML itself and applying some of GitHub's CSS onto it. It would be event better if we find a library to reliably render heat maps for us
