Update docs to use @deck.gl-community/editable-layers instead of nebula.gl

[AnJ-K]

Right now all the documentation for @deck.gl-community/editable-layers seem to lead to examples for nebula.gl with deck.gl version 8. Even if piece of code on the page is using community package, the link to the live preview of said code leads to codesandbox using nebula...

It is a bit confusing, especially to people who are new to deck.gl.
(And to LLMs, which are constantly injecting nebula imports, even when explicitly asked about community editable layers :P)

As an example I recreated the documentation for No React.
Example with webpack - https://stackblitz.com/edit/webpack-webpack-js-org-rbeazjjx?file=src%2Findex.js
Example with vite with hot reload - https://stackblitz.com/edit/vitejs-vite-mxvm9yfm?file=src%2Fmain.js

I could try updating at least some of the docs if you are interested.
If so, what do you think about stackblitz as well? I personally had easier time recreating the example over on stackblitz than on codesandbox.

On that note, I also propose to focus more on non-react examples. I don't know the percentage, but it would be for sure helpful to larger group of people.
