deleted reference to Atom in hello-ml5 docs

Dear ml5 community,

I'm making a Pull Request(PR). Please see the details below.

→ Atom Deleted from beginner docs

I noticed that Atom was listed on the webpage for ml5-library/docs/tutorials/hello-ml5.md

As Atom will be archived on December 15th, I thought it would be best to remove it as a suggested text editor, especially as the documentation is aimed at beginners.

I've removed mention of Atom from the relevant file.

You could replace Atom with Pulsar.
It is a fork from Atom and has seen a lot of updates and fixes.
