Automate adding/updating libraries list on the website

[prisonerjohn]

The list comes from the processing-contributions repo.

Notes from @runemadsen :

• There's a npm run updateContributions script that needs to be run in the processing-website repo while the processing-contributions folder is in the same parent folder. That will move the JSON files to the website repo, and then a commit just needs to be made with the new files.
• The website is deployed to AWS S3 and AWS Cloudfront via a GitHub action in the processing-website repo.

Hey @prisonerjohn :) Thanks for setting up this issue. The processing-contributions link is 404 for me. Is it a private repo?

Hey @SableRaf I don't remember why we made that repo private so I don't want to make it public just yet. I just added you to the website group which should give you access.
