Following the pattern from other repos, split the E2E test job into a
default job that runs a single default-only test always on PRs and a
full job that runs the full matrix when the ready-to-test label is
added.

Use the new ability of the shared E2E GHA to configure the Kubernetes
version. Add jobs that cover the latest available patch versions
(limited by kind images) from the three most recent minor versions.
Only run one E2E job with all-default configuration per K8s version, for
some coverage with minimal overhead.
