[Umbrella] Improve showcase

@dai-shi in the future, I'll write articles about jotai and deep dive in it.

@LuckyPigeon
It's ready. We have one example ./examples/hello.
This can work both locally or in codesandbox. If it runs locally it will use the local jotai src, if in codesandbox it will use the published jotai package. http://githubbox.com/pmndrs/jotai/tree/master/examples/hello

Would you try adding another example as a start?

[LuckyPigeon]

I can work on this, and would you prefer all the code in a PR or separate them into a few PR, for example, an example a PR?
Does this repo has a gitter or slack or any other contact method?
I have already gain some progress on "Hack New Example" and hope could keep working on it

[dai-shi]

Good question. For the time being, I'd just put codesandbox/github links in showcase.md.
We also have examples folder in the repo, and we'd like to improve it eventually.

We do have a channel in the pmndrs discord server. please find the discord badge in readme.

@dai-shi
I guess I need to split this to several PRs, at least a PR for one enhancement. I will start from adding descriptions.

[dai-shi]

Sure. That's expected.

@dai-shi
Is there a way to modify and commit the code in the showcase(codesandbox)?

[dai-shi]

@LuckyPigeon No. Just fork it and replace with the new URL.

@dai-shi
github can easily link to codesandbox by change https://github.com/<repo_name> to https://githubbox.com/<repo_name>.
Due to this feature, is it a good idea that we download all of examples in showcase.md and put them into examples folder?
Then we can modify and commit it easily, and we can also connect to codesandbox as easy as before.

@LuckyPigeon Alright, I understand your suggestion. I was going to work on examples some time later, but as you express your motivation, let me work a bit on examples folder so that you can put multiple examples in different folders. Hold on a moment.

[LuckyPigeon]

@dai-shi
Sure!

[dai-shi]

Let me close this as the initial iteration is done.
We'd want more examples official/unofficial.
Suggestions are welcome.
