docs: use latest image tags in examples (#1383)

The README's Docker example and the Docker and Kubernetes examples pointed at `nightly` images, while the README recommends `latest-dind`. Deployments copied from them should run the latest release, not a build of `main`.

None of the examples changed since v5.3.0, so they work as written with the current `latest` tags.

 The volumes keep the registration and the image cache across container recreation. The image reads more variables, such as `GITEA_RUNNER_LABELS` and `CONFIG_FILE`, see [scripts/run.sh](scripts/run.sh) and the [Docker example](examples/docker/README.md).
