Import the artifactapi access binding stranded outside state

The apply that created authentik_policy_binding.app_access["akP-artifactapi-admin"]
read it back off the Authentik Postgres read replica before the row had
replicated, got a 404, and dropped it, leaving main red.

Import the existing binding c9f22628-d48c-477b-b9ac-a952c7d081ce into state.
