Pull bind CRDs from operator repo instead of vendoring

References the CRD bundle from the bind-operator repo by a stable raw URL
so the CRDs never drift from the operator, matching how other apps import
upstream manifests.

- replace the nine vendored crds/*.yaml with a single remote resource:
  git.unkin.net/unkin/bind-operator raw config/crd/install.yaml at v0.1.1
- bump the operator image to v0.1.1 so the running operator and its CRDs
  come from the same tag

apps/base/bind-system/deployment.yaml
