chore(Containerfile): remove specific version constraints for system dependencies

Remove version constraints for system dependencies in the Containerfile
to simplify maintenance and ensure compatibility with the latest security
updates. This change allows the container to always use the most recent
versions of the packages, reducing the risk of vulnerabilities and
improving the overall security posture of the application.
