Can we configure with the new arc the default runner set image by composing with our own?

[gpadmesh]

We deployed arc system and runner scale set

helm install arc
--namespace "${NAMESPACE}"
--create-namespace
oci://ghcr.io/actions/actions-runner-controller-charts/gha-runner-scale-set-controller

helm install "${INSTALLATION_NAME}"
--namespace "${NAMESPACE}"
--create-namespace
--set githubConfigUrl="${GITHUB_CONFIG_URL}"
--set githubConfigSecret.github_token="${GITHUB_PAT}"
oci://ghcr.io/actions/actions-runner-controller-charts/gha-runner-scale-set
This install works like a charm but the problem is the base image has minimum packages but nowhere compared to GitHub-hosted runner docker images.

template:
spec:
containers:
- name: runner
image: ghcr.io/actions/actions-runner:latest
command: ["/home/runner/run.sh"]

    composing a docker image from this https://github.com/actions/actions-runner-controller/blob/master/runner/actions-runner-dind.ubuntu-22.04.dockerfile or any other ubuntu dockerfile. The docker image completes the build successfully. However, when we specify in the values.yaml the docker image the docker container starts but we have this error message

Defaulted container "runner" out of: runner, dind, init-dind-externals (init)
Waiting for docker to be ready.

Do we have any step by step instructions on configuring our own docker image?
