[Bug]: 18.react.dev is showing the docs for React v19.2

[thelastnode]

Summary

When opening any page on 18.react.dev - this one, for example - the page will show the React v19 docs, including things like the new useEffectEvent hook. This makes it difficult to see what is supported in v18 (for codebases that haven't migrated yet).

Speculating: I think setting 18.react.dev to point to the v18 branch in this repo should resolve this?
