Refactor manual-install Compose.yml: Simplify Environment Variables (#5459)

* 🔧 Refactor manual-install Compose.yml: Simplify Environment Variables

- Removed explicit values for environment variables in `docker-compose.yml`.
- Utilized default values for better flexibility and maintainability.
- Updated network configuration to use the default bridge driver.

Note: Using `network: default` is sufficient within Docker Compose; there's no need to create a separate `nextcloud-network` for all hosts. 🚀
