It's necessary to update to the `latest` image because the `latest-msmtp` image is now unmaintained and doesn't support postgres 17. However, this means we need to adjust things (the backup script and the environment variable config) because we need to use the latest notification mechanism, `apprise` instead of msmtp. Tested, seems to be working.
