[#62748570]Fix erroneous syntax for set_notification.
Merge branch 'master' of github.com:rhomobile/rhomobile-docs
Add version.rb to track versions and change config.ru to use that version instead of hard coded versions.
Further modifications to version.rb and config.ru
Change config.ru to hard-coded for 2.2 redirects as those URLs have the 2.2 version specified in them.
