First published draft

Dear all,

we finally have a first published draft of our CG specification of RDF* :)

https://w3c.github.io/rdf-star/cg-spec/2021-02-18.html

Please note that, for the sake of consistency, I have moved the editor's 
draft to

https://w3c.github.io/rdf-star/cg-spec/editors_draft.html

but the old URL should properly redirect.

   best
