feat(redis-ha): add EndpointSlices RBAC support (#394) (#409)

Kubernetes v1.33 deprecates the Endpoints API in favor of EndpointSlices
(discovery.k8s.io). Grant the redis-ha and haproxy Roles get access to
endpointslices alongside the existing endpoints permission so the chart
keeps working on newer clusters while remaining backward compatible.
