At the bottom of https://zio.dev/zio-prelude/, there's a link 🖊️ Edit this page pointing to https://github.com/zio/zio/edit/series/2.x/docs/zio-prelude/index.md. This though leads to a GitHub error page
404 - page not found
The series/2.x branch of zio does not contain the path docs/zio-prelude/index.md.
I suppose the link should instead point to https://github.com/zio/zio-prelude/edit/series/2.x/docs/index.md.
