fix(argument-specs): sync versions with defaults and add renovate tracking (#67)

* fix(argument-specs): sync versions with defaults and add renovate tracking

- Add k3s_channel and k3s_node_ip_max_pods to k3s argument_specs (fixes CI error)
- Fix docker_compose_v2_version default mismatch (5.1.0 → 5.1.1)
- Add renovate comments to argument_specs.yml version defaults
- Extend renovate.json customManager to cover argument_specs.yml files
  so versions are updated in the same PR as defaults/main.yml

* fix(k3s): remove unused k3s_node_ip_max_pods variable

The variable was defined in defaults but never referenced in any
template or task. k3s_max_pods covers the max-pods kubelet argument.
