Clarify contributing to website and hello.p5?

[peteruithoven]

I had a hard time finding the repo for the hello.p5 website and can't find the repo for the p5js.org website, could links to these repo's be added to pages like the Development page?

Hi, the p5js.org website repo is available here: https://github.com/processing/p5.js-website it is just under the processing group which is the same as this p5.js repo.

thanks @peteruithoven, I just added a "repositories" section to the dev page. please let me know if any of this needs further clarification, or feel free to make small edits as you see fit.
