    Get stable version using torbrowser updater xml
    
    The RecommendedTBBVersions file contains current versions of Tor Browser
    from all channels, including alpha or beta.
    
    Instead of this, we can use xml file used by Tor Browser's updater in
    the "release" channel:
    https://dist.torproject.org/torbrowser/update_2/release/Linux_x86_64-gcc3/x/en-US
