Add attribution links to each example description

[calebfoss]

I used the Github API to pull the blame for each example with Github username data. I then mapped that data to links and added them to the descriptions for each example. Finally, I made some manual tweaks based on contributors that were missing from the blame, such as @Malayvasa who contributed examples via p5 editor links.

Thanks @calebfoss. I'm still waiting for some previous contributors' feedback on this issue, like how to properly credit the contributors who worked on p5.js examples prior to the STF project, especially based on the fact that lots of p5.js examples were directly ported from examples on Processing website.

Meanwhile, @SableRaf is looking into getting clarification on processing website repo license issue.

I will come back to this PR after get more response from other contributors.

Hi @calebfoss ,

As part of considering #415, I’ve checked your attribution lists against the all_contributors list on the p5.js GitHub readme, and I see that the following contributors are not in the All Contributors list:

Darren Kessner https://github.com/dkessner
Animesh Sinha https://github.com/AnimeshSinha1309
Kathryn Lichlyter https://github.com/katlich112358
Greg Albers https://github.com/geealbers
Aaron Welles [undefined]
Marco Macarena https://github.com/macarena
Kristian Hamilton https://github.com/khamiltonuk
Keshav Gupta https://github.com/keshavg2
adil rabbani https://github.com/AdilRabbani
Ritesh Patil https://github.com/riteshsp2000
Gabriel Sroka https://github.com/gabrielsroka
Casey Conchinha https://github.com/kcconch
davidblitz https://github.com/davidblitz
crh82 https://github.com/crh82

All but one I can add using the bot in processing/p5.js#2309 (“add ___ for example”). The contributor without link I can add manually unless you have their GitHub @. (Edited to add: I just checked that it's possible to add a name only without a GitHub handle in my fork: https://github.com/ksen0/p5.js/)

For all contributors those that are already on the list, I can go through and ensure there’s an “example” emoji/contribution note:
