doc/install: fixed how JS defines browser OS

Updated "detectOS" function to use "userAgent" instead of "appVersion".
It has more info and using that it can be correctly detected that the
user uses Firefox on Linux. Users who want to be incognito can modify
these values in their browsers, so there is no workaround for such rare
cases. Added "else if" statements to prevent overwriting the variable.
Also, added a check that prevents to use "click" on "null" elements (in
case if OS haven't been detected or an element doesn't exist in DOM).

Fixes golang/go#41537
Fixes golang/go#41528
