GlobalDataverseCommunityConsortium vs. gdcc repo

Since https://github.com/GlobalDataverseCommunityConsortium/dataverse-previewers/pull/67 was recently closed in favor of https://github.com/gdcc/dataverse-previewers/pull/6 should text be added to the README for `GlobalDataverseCommunityConsortium` to indicated that pull requests should be made against the `gdcc` repo instead?
