runtime: Add kata-deploy as a dependency

kata-deploy helm chart provides the installation of kata-containers,
using the kata-containers own helm chart as a dependcy of this umbrella
helm chart for the Confidential Containers organization.

For now the repo uses x86_64 as the default architecture, and we have
kata-aarch64.yaml, kata-s390x.yaml, and kata-remote.yaml as values that
can be used to deploy this chart in different architectures.

We do NOT yet support heterogenoues (as in, different architectures)
deployments, but this is in the TODO list.

Documentation was vibe generated using Cursor AI.
