Detailed example attribution

[ksen0]

Addresses #415 - work in progress. Remains to be done:

• Support for cases where pre-2023 attribution is also collective e.g., Shape primitives
• Support for cases where there is no link for author (not sure if case exists)
• Once done on main, will need to be cherrypicked to 2.0 as well
• Ensure all people mentioned in any part of attribution is on all-contriutors in p5.js README in both main and dev-2.0 branches and include "example" emoji

Before

The license is at the bottom of the page, and attribution (inspired by and maintained by) is split.

(Then there is the sketch and the code - viewer has to scroll all the way down)

After

Considering showing the attribution more clearly. "p5.js Contributors" also points to all-contributors list in p5.js repo README, rather than the People page.

@ksen0 This looks great! I really appreciate the thoughtfulness of how you put this together.

One tiny tweak: it occurred to me that since the code was copied over to this repo in 2024, it should be "2024 onwards" rather than 2023.

This certainly does not need to be in this PR, but something to consider for the future: I think it would be helpful for readers to have some visual design distinction between the description and attribution. I'm picturing the ways that text publications design attribution information in articles. Italics is a common convention but may look awkward with this much text. Maybe just a slightly different background color?

Thank you again!
