📝 WalkthroughWalkthroughDocumentation for CA rotation procedures was reorganized and updated. Section headings were swapped to present Talos API rotation first, followed by Kubernetes cluster rotation. Command examples were changed from talosctl-based to talm-based workflows with explicit flag configurations, and post-rotation secret retrieval instructions were simplified. Changes

Code Review
This pull request significantly improves the documentation for CA rotation by providing clearer, step-by-step instructions for both Talos and Kubernetes CAs. The new structure with distinct dry-run steps is much easier to follow and safer for operators. I've added a few suggestions to further enhance clarity and consistency by providing specific commands for downloading new configurations and using consistent file paths as shown in other parts of the documentation.

| talm -f nodes/node.yaml rotate-ca --talos=true --kubernetes=false |

The filename nodes/node.yaml seems inconsistent with the talm setup guide (talm.md), which uses node-specific files like nodes/node1.yaml. To improve clarity and consistency across the documentation, consider using a more specific placeholder like nodes/node1.yaml or nodes/<your-node-file>.yaml. This comment applies to all talm commands in this file.
| talm -f nodes/node.yaml rotate-ca --talos=true --kubernetes=false | |
| talm -f nodes/node1.yaml rotate-ca --talos=true --kubernetes=false |
| ```bash | ||
| talm kubeconfig -f nodes/srv1.yaml | ||
| ``` | ||
| After the rotation is complete, download the new `talosconfig` from the secrets. |

The instruction "download the new talosconfig from the secrets" is a bit vague. To make the documentation more actionable for users, it would be very helpful to provide the specific command to download the new talosconfig. This would make the guide much easier to follow.
| talm -f nodes/node.yaml rotate-ca --talos=false --kubernetes=true --dry-run=false | ||
| ``` | ||

The instruction "download the new kubeconfig from the secrets" could be more specific. The talm setup guide shows using talm kubeconfig to get the configuration. It would be very helpful to include the full command here to make the documentation self-contained and easier to follow. For example:
talm kubeconfig -f nodes/node1.yaml > kubeconfig
