Transform a command to run under `bundle exec` with the same semantics as Ruby execution elsewhere in this system. That means you should end up with something like `/bin/ruby /bin/bundle exec /bin/ruby /bin/cmd args`.
@param cmd [String, Array<String>] Command to transform. @param path [String] Optional input path for command resolution. @return [String, Array<String>]
