This version is not retracted. It should be returned by the proxy's
@latest endpoint. It should match the @latest version query.

TODO(golang.org/issue/24031): the proxy and proxy.golang.org both return
the highest release version from the @latest endpoint, even if that
version is retracted, so there is no way for the go command to
discover an unretracted pseudo-version.
