Upgrade the python version in App Runner Service?

In the AppRunner service configuration (apprunner.yaml) there is an option of a container or runtime version (e.g. runtime: python3.10). You can use a CI/CD pipeline to build a container with the required Python version, then add the container to ECR and import it when creating a new AppRunner service.
