[Docs] [Form] “Fix” the framework dropdown

[juliendelort]

The framework dropdown has no effect when viewing a “core” page. Since users land on the Overview page (which is a “core” page), the dropdown looks broken, and it looks like we don’t support Vue (users have to go to a “react” page first before switching to “Vue”).

The dropdown should work even when seeing a core page, it should at least refresh the navigation menu to replace the React pages with the Vue pages.

As a side note, since the Overview page shows some React code, it may make sense to create an Overview/React and an Overview/Vue page (like in the TanStack Query docs)
