Change annotation property for title and description to dcterms version

[hoganwr]

The foundry is moving to eliminate the dce (Dublin Core elements) namespace annotation properties altogether.

The OBO Dashboard currently allows for either dce:title or dcterms:title, and for either dce:description or dcterms:description, but will eventually remove the permission for dce versions.

So this issue says to change OMRSE now to dcterms:title and dcterms:description.

NOTE: these are ontology annotations! (not class annotations or property annotations)
