test/e2e: fix `ginkgo ./test/e2e`

When running ginkgo directly against the source code of the test suite instead of using some pre-compiled e2e.test binary, ginkgo no longer recognized that it runs a Ginkgo testsuite, which broke "-focus" and "-p". By re-inserting the magic strings that ginkgo looks for into a comment, we can restore the desired behavior without affecting the code. Fixes: #74827
