commit ff05fbdf1fb4d68d519840d6f2007cf24064395f
Author: Ward Vandewege <ward at curii.com>

    18245: Update the "Ruby and Bundler" installation page:
    - installing the system bundler package is no longer needed
    - the RVM installation method already installs bundler, no need to do
      that explicitly
    - update the references to the latest Ruby 2.5.x version
    - remove reference to Ubuntu 16.04 which is no longer supported
    - update the "install from source" documentation to make it work with
      the Arvados rails packages
