Draft: Add new runner to extend Sylva CAPO resources with new platform

closes #726

This MR is to add a new runner for the Sylva CI to balance the resource allocation between two platforms for the capo based deployments.

For now, we are planning to move the following deployments to rocket:

• capo-kubeadm
• capo-fip
• capo-rke2-oci
• capo-rke2-suse-os
