dependencies: ginkgo v2.19.0, gomega v1.33.1

Ginkgo v2.18.0 allows tweaking the output so that
it's easier to follow while a job runs in
Prow (https://github.com/onsi/ginkgo/issues/1347). Using this in
hack/ginkgo-e2e.sh will follow in a separate commit.

Gomega gets bumped to the latest release to keep it up-to-date.

Ginkgo v1.19.0 adds support for --label-filter with labels that represent
sets (like our Feature:<Foo>).
