Switch documentation page to English always leads to home page

[crisz]

Hello, visiting the documentation with a browser localized in Italian, the following banner appears:

However, the link "documentation in English" always leads to the following page: https://expressjs.com/, while it would be expected that the currently visualized page just gets switched to English, removing the "/it/" from the URL.

This is particularly annoying because the translated pages are usually low quality or obsolete, and thus a manual intervention is required all the times.

I'd also argue whether is the case to localize a technical page in Italian and provide it by default.
