(Maint) Add heira to Gemfile so that you can run it

Without hiera itself being referenced in the Gemfile you can't run
"bundle exec hiera" to try out the command line app. This adds hiera as
a referenced gem to enable that (this is also done in puppet and facter,
so this should bring hiera in line with those).
