- Updated `backup.sh` to allow backing up multiple databases by introducing the `DATABASE_NAMES` environment variable. - Modified `env.sh` to handle the new `DATABASE_NAMES` variable and ensure compatibility with existing `DATABASE_NAME`. - Updated `docker-compose.yaml` and `README.md` to reflect changes and provide examples for backing up single and multiple databases. - Added a new binary file `umb_pm_dev.bacpac` for database backup.
