[PATCH 1/1] switch debian snapshot mirror to snapshot.debian.org

[Felix Moessbauer]

The cloudflare mirror is not updated since may 2024. By that, other
projects like reproducible-containers switched back to the "official"
snapshot.d.o mirror, after being informed by me.

Having an outdated upstream mirror poses the risk of being
"non-reproducible", just because the SDE is more recent than the latest
snapshot and once the mirror is updated, a more recent snapshot is taken
(due to the redirect-to-latest logic of the snapshot mirror).

This patch also switches the debian mirror to snapshot.debian.org to at
least use an official and maintained mirror. In case downstream users
run into rate-limiting issues, they still can switch to other mirrors.
