deploy: do not fail when the MinIO images cannot be pulled

minio/minio and minio/mc no longer exist on Docker Hub or Quay, so
docker compose pull fails and, with script_stop, ends every deploy
before anything is applied.

Ignore pull failures. Postgres is still updated; MinIO and its init
container run from the copies cached on the host.
