Not possible to use postgres image config in the helm chart

What's the issue?

There is section in the dagster helm chart values to configure the postgresql:

postgresql:
  # set postgresql.enabled to be false to disable deploy of a PostgreSQL database and use an
  # existing external PostgreSQL database
  enabled: true

  # Used by init container to check that db is running. (Even if enabled:false)
  image:
    repository: "library/postgres"
    tag: "14.6"
    pullPolicy: IfNotPresent

This image is used both for webserver / daemon init images as well as for the database via bitnami helm. It is not possible to change that value to some other registry.

And this impossibility arises from the fact that in dagster helm repository and tag are composed to url as {repository}:{tag}. While in bitnami they are composed to url as docker.io/{repository}:{tag}.

It should be able to disable that docker.io prefix by setting image.registry to null and global.imageRegistry to null, but it does not seem to work.

What did you expect to happen?

Setting repository + tag should work in postgresql sections like it works in other sections
