dependencies: update ginkgo to v2.7.0

The new ginkgo release adds sorting of specs. This was triggered by
the observation that parallel test execution of Kubernetes E2E tests
sometimes ran the same spec twice and (presumably) other specs not at all
because spec order was random due to iteration over a map.

Sorting should avoid that problem.
