+- Don't crash during `release upgrade` for SDP 25.11.
+  Previously it errored with `HTTP status client error (404 Not Found) for url (https://raw.githubusercontent.com/stackabletech/secret-operator/main/deploy/helm/secret-operator/crds/crds.yaml)`, as the secret-operator now maintains the CRD itself ([#418]).
