[imsc] Nested ruby should not be allowed

cconcolato has just created a new issue for https://github.com/w3c/imsc:

== Nested ruby should not be allowed ==
In IMSCvNext, the current text allows nested ruby because the #ruby feature is permitted and this one is defined as:

> A TTML presentation processor supports the #ruby feature if it implements presentation semantic support for all defined values of the tts:ruby attribute in both nested and non-nested contexts.

The #ruby feature should be prohibited, and the #ruby-non-nested should remain permitted.
