Manuel Simón Nóvoa 64269bea22 Docs: Migrate etcd troubleshooting guide from RKE/Docker to RKE2/K3s/containerd
- Updates `troubleshooting-etcd-nodes.md` to replace Docker-based commands with `crictl` and `etcdctl` for RKE2 and K3s.
- Replaces `curl` connectivity checks with `openssl s_client` to support etcd 3.5+ gRPC requirements and isolate transport layer testing.
- Adds prerequisites section with necessary environment exports.
- Updates all `etcdctl` commands to use explicit inline certificate paths for RKE2 and K3s.
- Replaces shell-dependent container commands with host-side processing to support distroless images.
- Updates log level configuration instructions for RKE2/K3s config files.
