dhi.io/redis-chart:23.0.5 does not work because dhi.io/kubectl:1.34.3-debian13 does not include bash

I've recently tried switching from bitnami/redis to dhi.io/redis-chart.

Out the box (using default images from the values.yaml) this does not work because the default image of dhi.io/kubectl:1.34.3-debian13 does not include bash (and perhaps other commands) and isn't able to execute the script /opt/docker/scripts/kubectl-scripts/update-master-label.sh.

I've worked around this by passing the following helm values to use the -dev variant image:

kubectl:
  image:
    tag: 1.34.3-debian13-dev
    digest: ""

I'm not 100% sure how these images are being built, but looking at this file: https://github.com/docker-hardened-images/catalog/blob/b23b7c3d5262862a937e8db73b611eaa813844e9/image/kubectl/debian-13/1.34.yaml

It does seem to suggest that bash should be included in the image based on the catalog file, but after a docker export of the image and looking at what it includes it does not.

I guess I have a few questions:

• Why is bash not included in the current image as of today? It was updated approx ~16 hours ago.
• How can the catalog repo be used to build a new image locally?

For me this situation showed up running a HA config with sentinel. Otherwise for a standalone deployment none of this is an issue.
