Explicitly configure the port for catalogue to be 80 in kubernetes/manifests

In case one was to fork this repository and pass arbitrary arguments without passing `-port=80`, `catalogue` would then suddenly no longer work, as: - `catalogue` defaults to `8081`: https://github.com/microservices-demo/catalogue/blob/0.3.5/cmd/cataloguesvc/main.go#L44 - the default override in `Dockerfile` would then be lost: https://github.com/microservices-demo/catalogue/blob/0.3.5/docker/catalogue/Dockerfile#L12 - `/health` therefore wouldn't be reachable on `80` (but `8081`) - Kubernetes therefore wouldn't route traffic to `catalogue`
