ci: Update the newer Kubernetes version to v1.33.0 (#147)

k8s-snap currently does not support patch-level upgrades (if a new node
joins that has a different patch number, it will be rejected).

Bump the newer Kubernetes version to v1.33.0 as a result. This should
allow the integration test "Workload cluster upgrade" to pass.
