colocated_python_sidecar container is not accessible on us-docker.pkg.dev

[sidecar/python/Dockerfile](https://github.com/AI-Hypercomputer/pathways-utils/blob/main/pathwaysutils/sidecar/python/Dockerfile) mentions `us-docker.pkg.dev/cloud-tpu-v2-images/pathways/colocated_python_server` as the base image. However this not accessible (both with `docker pull` and by going to that URL). In contrast, both - `us-docker.pkg.dev/cloud-tpu-v2-images/pathways/server` - `us-docker.pkg.dev/cloud-tpu-v2-images/pathways/proxy_server` are accessible via both `docker pull` and directly in the browser. Could you please make `colocated_python_server` public too? For context, I'm trying to follow [this GCP guide](https://docs.cloud.google.com/ai-hypercomputer/docs/workloads/pathways-on-cloud/porting-jax-workloads#data-loading) which "strongly recommend co-locating your input data pipeline by using [colocated Python](https://docs.cloud.google.com/ai-hypercomputer/docs/workloads/pathways-on-cloud/porting-jax-workloads#colocated-python) to run your data pipeline directly on the accelerators".
