fix: Get rid of spammy RBAC log

[skhalash]

Description

Changes proposed in this pull request (what was done and why):

• Operator container was printing the following log message:

{"level":"ERROR","timestamp":"2024-10-22T15:15:54Z","caller":"cache/reflector.go:158","message":"Unhandled Error","logger":"UnhandledError","error":"pkg/mod/k8s.io/[email protected]/tools/
cache/reflector.go:243: Failed to watch *v1.CustomResourceDefinition: unknown (get customresourcedefinitions.apiextensions.k8s.io)"

Even though the watch permissions is not required, the operator is already granted get and list permissions, so adding watch to satisfy controller-runtime is fine.
