MIssing permission to query endpointslices

[AlexShemeshWix]

Hi I can see that victoria-metrics-agent chart includes endpointslices as role for kubernetes_sd_config sections in scrape configuration. But ClusterRole definition in clusterrole.yaml is lacking permission for endpoinslices resource. When i deploy this chart it wont scrape from endpointslices because of lacking permissions. Please add endpointslices resource to ClusterRole definition.
