Fails to run in GitLab with privileged runner

[SNThrailkill]

In conjunction with #881 I tried to get around this issue by running the pipeline with a privileged kubernetes executor with the following config:

[[runners]]
      [runners.kubernetes]
        privileged = true
        [[runners.kubernetes.volumes.host_path]]
          name = "docker"
          mount_path = "/var/run/docker.sock"
          host_path = "/var/run/docker.sock"

Which results in the following error:

sudo podman run --privileged --security-opt label=type:unconfined_t \ # collapsed multi-line command

The Kubernetes nodes themselves are running Ubuntu 24.04 with docker installed.
