Fix deployer helm chart so that runtime picks the correct docker image (

LangStream#180)

* Fix Deployer Helm Chart

1. Fix the deployer helm chart so that the runtime picks the proper docker image.
2. minio-dev.yaml picks a volume that is read only in GKE.
3. Update instructions

* Yet another place to provide the runtime image
