Added example jupyter notebook into the examples folders

[kolibril13]

As there are some example .py scenes, I think a notebook example is a good addition.

Depends on #1013

I'm fine with adding an example notebook, but I'd strongly suggest not including cell output when doing so.

[kolibril13]

yep, good point, I will remove it.

As it is convenient to store jupyter notebooks in the manim project folder, I added the jupyter/ folder to the gitignore which ensures that the notebooks are not version controlled.

Can this be merged @behackl ?

With #1013, the syntax for jupyter notebooks would change and the sample provided would end up failing. I'm not sure how to test that the notebooks runs without error, but a test case that can be run with pytest would be helpful to ensure the notebook runs properly.

Output has been removed.

Here is how the binder link looks now in the docs: https://manimce--1029.org.readthedocs.build/en/1029/installation.html

Two more suggestions, and one further recommendation: I think it would be good if the example notebook also made use of the newly introduced config.media_width option. A new cell containing something like

# set the maximum width for video outputs to a predefined value
config.media_width = "42%"

should be enough. Then this is (finally) ready to merge, from my point of view.

Depends on #1013.
I just tried it, and without #1013 this is not working currently:

I'm generally unsure what the appropriate label for this PR is. Maybe documentation?

🎉 Great news! Looks like all the dependencies have been resolved:

• Refactored the Command Line Interface to use Click instead of Argparse #1013

💡 To add or remove a dependency please update this issue/PR description.

Resolved the merge conflict and tested locally: LGTM.

(The banner animation seems to be currently broken though, which is unfortunate.)
