[bug] Sharing link to documentation from mobile Chrome drops version from the URL

I noticed that if I use "share" tool in mobile Chrome (Android and iPadOS are affected at least) version part is removed from the final URL. E.g.:

When I do share from the page
```
https://docs.conan.io/2/ci_tutorial/project_setup.html
```
that will be ended as
```
https://docs.conan.io/ci_tutorial/project_setup.html
```
I.e. `2` part is removed from the URL. And I see 404 [Page Not Found](https://docs.conan.io/ci_tutorial/project_setup.html#page-not-found) error in result.

Similar behavior for legacy 1.x links. When I want to share link from the page `https://docs.conan.io/1/index.html` I will end up with `https://docs.conan.io/index.html` redirected to the `https://docs.conan.io/2/`. That's obviously not what I want to see.
