feat(chart): add replicaCount to allow scaling external-dns to 0 or 1 (#6503)

The Deployment hardcoded replicas: 1 with no way to override it, so the
chart could not be scaled to 0 (e.g. to temporarily pause external-dns)
without forking. Add a replicaCount value wired into the Deployment.

external-dns does not support leader election, so running more than one
replica causes duplicate/conflicting DNS updates. The value is therefore
bounded to 0 or 1 in values.schema.json (minimum 0, maximum 1) and is
enforced again by a template-level guard for paths that skip schema
validation, such as helm template piped into kubectl apply. Unit tests
cover scaling to 0 and rejecting values above 1. This addresses the
concern that blocked the earlier replicaCount PR.
