RIP Atom - Update to Hello ml5.js - A gentle introduction to ml5

[Yasmin-A95]

Dear ml5 community,

I'm submitting a new issue. Please see the details below.

I soon-to-be outdated information on your website which may make it less beginner friendly, details are as follows:

I noticed that Atom is listed as a suggested text editor in ml5-library/docs/tutorials/hello-ml5.md

Atom is due to be archived on December 15 2022 so it might be worth removing it as a suggested editor, so new people aren't confused or potentially being directed to a site that doesn't exist anymore.

Here's some helpful screenshots of the outdated information

Here's some extra information about where to find the issue in question

Hey @Yasmin-A95 thanks for raising this! Good catch, sorry for the late reaction. Maybe we could substitute the link to Atom with a link the the p5 web-editor, which works pretty well with ml5 and requires no installation at all. Unfortunately there is no real landing page for the p5 web editor.
I will try to contribute a page to the p5 web page, than we can link it here.
Linking @joeyklee or @bomanimc who might be able to merge your PR.
Thanks for your contribution.

No worries @tlsaeger, let me know when you've got the landing page finished.
