DRA drivers must provide ResourceSlices using the v1beta2 API types.
The controller then converts under the hood to v1beta1 if needed, i.e.
drivers are compatible with Kubernetes 1.32 and Kubernetes 1.33, as
long as at least one beta API group is enabled.
Testing pivots from using v1beta1 as the main API to v1beta2, with only one
test case exercising v1beta1.
