Broken sandbox examples

[Pringels]

It looks like the example sandboxes no longer work:
https://m94xb.csb.app/
https://5jgjz.csb.app/

Could be due to the repository migration to pmndrs?
I suspect that the sandbox is getting a 404 when it tries to pull the example code from github.

Looks like the redirect rules aren't catching all urls:
https://github.com/react-spring/react-postprocessing/master/examples/bubbles <- returns 404

I would attempt to create a PR but I assume the sandbox owner would have to update the project settings manually :)

Looks like the code sandbox links are still broken :/

specifically, it seems that quite a few all yield the same error:
