fix(ci/debianrepo): avoid running docker arm64 (#551)

The issue at https://github.com/ooni/probe/issues/1741 is that running `docker --platform linux/arm64` segfaults when running `sudo apt-get update -q` inside the `arm64` docker environment.

As far as the `debianrepo` rule is concerned, we can fix the issue by taking advantage of Debian multi-arch. We now configure Debian multi-arch and install the package inside a `debian:stable` environment.

We keep using docker. In principle we could not. But the Ubuntu environment provided by GitHub actions does not support multi-arch for arm. Also, I'd like testing this rule to be possible also locally (where I don't have Debian).
