Subject: [PATCH] Update Dockerfile with custom base image and add healthcheck

- Update base image to `docker.io/library/alpine:3.18.4` to ensure the
latest version is used.
- Set the user in the container to `notatio` for security purposes.
- Add a healthcheck to monitor the app's availability.
- Modify the `ENTRYPOINT` to delay the execution by 10 seconds before
starting the application.
