does spicedb have an HTTP health check endpoint? our envoy sidecars need to healthcheck the pod running the spicedb image using either HTTP or TCP but we suspect using the latter against the HTTP port 8443 prevents normal HTTP traffic from resolving somehow

we expose the gRPC health service, so it should be exposed in HTTP as well

yaml
  spicedb:
    image: authzed/spicedb
    command: serve 
    environment:
      - "SPICEDB_GRPC_PRESHARED_KEY=randomkey"
    ports:
      - '50051:50051'
    healthcheck:
      test: ["CMD", "grpc_health_probe", "-v", "--addr", "localhost:50051", "-connect-timeout", "180s"]

This is how we ensure in test env that its ready
