Kubernetes Docker in Docker Deployment with gitea-runner

NOTE: Docker in Docker (dind) requires elevated privileges on Kubernetes. The current way to achieve this is to set the pod SecurityContext to privileged. Keep in mind that this is a potential security issue that has the potential for a malicious application to break out of the container context.

NOTE: dind-docker.yaml uses the native sidecar pattern (init container with restartPolicy: Always), which requires Kubernetes 1.29+ (or 1.28 with the SidecarContainers feature gate).

NOTE: A helm chart for gitea-runner also exists for easier deployments https://gitea.com/gitea/helm-actions
