The alias for vendor/github.com/onsi/ginkgo/ginkgo ensures that code like
30e99cb2a9/experiment/kind-conformance-image-e2e.sh (L110)
continues to work. The one without "vendor/" is there just in case that it
was used because it also worked.
Long term, "ginkgo" is a nicer, version independent alias. It gets used
internally to avoid future churn and gets documented also publicly in the
Makefile help.
The caveat is that there's no guarantee that a future v3 CLI will be compatible
with current invocations. But the most common usage is through
hack/ginkgo-e2e.sh, which can deal with such differences.
