Talm init with cozystack preset produces outdated repository config #39

Steps to reproduce:
Run Talm init --preset cozystack

In values.yaml:
image: "ghcr.io/aenix-io/cozystack/talos:v1.9.3" (should point to image: "ghcr.io/cozystack/cozystack/talos:v1.9.3"

In Chart.yaml:
templateOptions.talosVersion: "v1.8" (should probably be "v1.9.3")

Other stuff might be outdated as well, as I just started out with cozystack I'm not yet super familiar with all the settings.
