Merge master into staging-next

- `programs.goldwarden` has been removed, due to the software not working with newer versions of the Bitwarden and Vaultwarden servers, as well as it being abandoned upstream.

- The `chatgpt-retrieval-plugin` package and `services.chatgpt-retrieval-plugin` module were removed due to the package having been broken since at least November 2024.

- The `cardboard` package and `programs.cardboard` module were removed due to the package having been broken since at least November 2024.

- The default `kops` version is now 1.33.0 and versions 1.30 and older have been dropped. See [Upgrading Kubernetes](https://kops.sigs.k8s.io/tutorial/upgrading-kubernetes/) for instructions on how to update kOps.
