Make label definition consistent and internationalized, rather than follow W3C annotations about trc

[mejackreed]

From a practical viewer implementation standpoint, we may still want/have to account for the label as a string when consuming annotations from an external WebAnnotation server that may not have the IIIF context. 👍 for the push for consistency.

As discuss in the May 2019 Call, the issue would be clearer if the example showed a label on an Annotation or an AnnotationCollection. The current example may be correct but it's a bit indirect...

For the record, from the call: IIIF/api#1834 (comment)

And the discussion on this is reasserting the IIIF context over the Web Annotation context within AnnotationCollections and enforcing the expectation that it is a language map. Although WA also uses rdfs:label, the IIIF context adds details that are not included and the WA model states "the value must be a string" at https://www.w3.org/TR/annotation-model/#annotation-collection
