Added neat projects from example_scenes folder

[kolibril13]

As title.
One more chapter for the docs

[kolibril13]

I think we should reduce example_scenes/basic.py to only 3 very nice looking examples and get rid of the rest.
Also in this PR, I think now every example are super necessary.
What do you think, which one should be removed?
See here:

The name of the page doesn't make sense for these; they aren't projects.

[kolibril13]

I partly agree on that.
I thought they are small projects, that users can discover easily.
But what would be alternatives, @eulertour ?
Maybe somethink like "Manim Overview"?
Or "Basic Scenes"
But I think neat projects is a good title when we would add one sentence like:
"In this section you can see some scenes that will help you to get to know manim in several contexts"

[eulertour]

Since we don't have any projects listed yet we can just rename it to "Examples" and create a projects page when we've decided on some to showcase.

As Examples is already the chapter name, I don't like the subchapter to have the same name.
See here:https://manimce.readthedocs.io/en/latest/examples.html
I would be also fine with "Demonstration of manim", "Our Favorite Scenes".

And I just had the idea of a new section called "Release Highlights" for new features, that are not possible in the 3b1b version

What is the difference between the current "neat projects" and "advanced examples"? I think we can put these under "advanced" for now.

[eulertour]

This is fine for now but we should update it with examples that are advanced when we find some.

[eulertour]

I didn't realize you were taking the examples out of examples/basic.py. Those provided a quick way to see how updaters and tex rendering worked, so they should be replaced.

[leotrs]

Uuuh I didn't realize this either. @kolibril13 next time please add a more precise description of all changes you are making. In order to do this, I suggest you use the PR template.

Also, @reviewers (me included), let's pay more attention to what we are reviewing 😅

I interpreted the thumbs up as a sign that this would be ok. But alright, I will add them back! :)
