APT should probably use HTTPS for getting packages

[AdamLeyshon]

As of recent, it seems Fastly CDN which powers Debian's APT repos, no longer serves HTTP requests.
They also have not redirected HTTP to HTTPS either, though even if they did I'm not sure APT would follow it.

When using FROM rust:1.68.2-slim-bullseye

But a simple sed fixes this:

RUN sed -i 's|http://|https://|g' /etc/apt/sources.list

You should make this request to the maintainers of the Debian base image we build off of.
