docker pull unauthenticated

Version
docker image: 2.24.1

Describe the bug
I have setup pulp in order to use it as Pull-Through Caching server for containers.
If u authenticate as admin by putting the base64 username:password in the docker config it works.
If i try to pull a already pulled image without authentication it does not work.

To Reproduce
I can pull docker image using docker when i put the base64 authentication in the config. But without authentication it does not work (token disabled)
Without credentials i get "Error response from daemon: Head https://<server>/v2/docker-cache/gitlab/gitlab-ce/manifests/17.9.3-ce.0 no basic auth credentials"

Expected behavior
Ability to pull unauthenticated the container using docker.

Additional context
pulp-dev: gerrod:
Right now our non-token auth code is setup based on how podman works. A logout podman will send the auth header Basic Og== which we use to specify an anonymous user. Docker on the other hand will send no auth header and when it requests the /v2/ endpoint it hits the 401 error because that endpoint expects atleast an anon user.

We should probably just change this hardcoded line: https://github.com/pulp/pulp_container/blob/main/pulp_container/app/registry_api.py#L474

Start in pulp_container/app/registry_api.py at the hardcoded line near 474 and trace how unauthenticated requests to the /v2/ endpoint are handled. Reproduce the Docker pull without credentials, then verify that an already cached image can be pulled successfully without authentication.
