Update Dockerfile.debian

When setting the DEBIAN_FRONTEND environment variable, it's best to apply it directly to apt commands rather than setting it globally. If DEBIAN_FRONTEND=noninteractive is set as a persistent environment variable in the container image, it can affect other Debian-specific commands run after the container starts, potentially leading to unintended behavior.

Instead, consider using it like this:

DEBIAN_FRONTEND=noninteractive apt-get update
DEBIAN_FRONTEND=noninteractive apt-get install ...

This ensures the variable is only active during the apt operations and isn't retained in the final image, preventing any lingering side effects.
