fix(cla): point the agreement link at the canonical repository (ENG-2017)

Both URLs the org uses for this document are rename redirects that resolve to
the same repository and serve byte-identical content. A redirect is fine until
somebody creates a repository at the old name, and this is the page a
contributor reads before agreeing to it. Name the repository that actually
holds the file.
