Outdated link on https://ivoa.net/rdf

[Dubois-Felsmann, Gregory P.]

At the bottom of the page https://ivoa.net, it says

"To learn how to work with and improve IVOA vocabularies, see Vocabularies in the VO 2."

with a link to a *working draft* of that document (http://ivoa.net/documents/Vocabularies/20200326/).

The v2.0 REC is https://www.ivoa.net/Documents/Vocabularies/20210525/index.html
and has since been superseded by v2.1:
https://www.ivoa.net/Documents/Vocabularies/20230206/index.html

The WD link should probably be replaced by one of the above.

Best wishes,
Gregory
