issues with the new 2D advection-diffusion example

[slayoo]

@pawelmagnu, here's an update on the post-merge status for #427:

• animation is not properly uploaded to "tip" release (file not found error in the logs) - this blocks upload to PyPI
• when executing on mybinder.org, there is "ModuleNotFoundError: No module named 'imageio'" error
• Colab badge in the notebook has wrong URL
• there is no link/badge in the examples/README.md leading to the new examples
• figures in the notebook are not displayed when viewed on GitHub - there are just blank white panels
• no "view on github" badge in the notebook
• some header comment with a hint on what is being computed in the notebook would be very helpful

Let's aim at fixing it next week

@Kojec1 could you check which points have already been addressed in #456 ?

There's still an issue with the figures displayed on GitHub, missing header information and I haven't managed to check if the .gif file is successfully uploaded to the "tip" release. The other issues seem to be solve.

[pawelmagnu]

I'm pretty sure we can't check if the .gif file uploads before actually merging to main.

.gif file upload works!
The notebook does not work on Colab yet as it fails on first line with:

This is due to lack of pip install ... commands for Colab in an initial notebook cell, like we do in other notebooks.
Here's a PR addressing it: #458

Just tested both on Colab and mybinder.org, and everything works!
So, we're still missing two things:

• figures in the notebook are not displayed when viewed on GitHub - notebook was committed with cell output cleared
• some header comment with a hint on what is being computed in the notebook would be very helpful
