Links to older versions broken with new build

[RicardoM17]

The links from current master no longer redirect to the same page in the older version but instead redirect to the main docs page.

Also for V1.10 it redirects to the QGC docs instead.

Issue raised by Andrew Saba on PX4 slack #documentation channel

FYI, the current master documentation page, when you switch versions it redirects back to the home page of the documentation. Older versions would keep you on the same doc page but grab an older version. Is this intentional/something thats not easy to fix?
Also, more of a bug, when switching to the v1.10 version, it redirects to the QGC docs page. Im guessing thats a bug? I can open an issue if you want. Tested in Firefox on ubuntu 18.04. All other versions go to PX4 docs as expected.

Known issue. Not easy to fix.

Yes, that's a bug. I will fix tomorrow.

I am closing this. The requirement for the version switcher is more precisely noted in #872
Thanks!
