pin k8s version (#43)

The kubectl-helm-minikube devcontainer feature pulls https://dl.k8s.io/release/stable.txt
(https://github.com/devcontainers/features/blob/main/src/kubectl-helm-minikube/install.sh#L167) when latest is specified as a version, but this file sometimes fails to load, breaking the build. Pinning a specific version bypasses this.
