app-admin/puppet: fix dev-ruby/rgen dependencies

The code does feature detection so it does not concern itself with versions.
The feature detected was first introduced in 0.6.5, but the notice shown when
the feature is not present mentions installing 0.7.0 or better. In any case we
should not limit this dependency to exclude newer versions.

Package-Manager: portage-2.2.20.1
