Fix base image inconsistency in reprobuild for noble & resolute

[ShahanaFarooqui]

cln-repro-* images use minimal debootstrapped base images (jammy, noble, resolute) with additional layers from contrib/reprobuild/. Currently, Dockerfile.noble and Dockerfile.resolute incorrectly pull from ubuntu:noble and ubuntu:resolute instead of using the debootstrapped noble and resolute base images, breaking consistency with Dockerfile.jammy. This PR corrects the base images for noble and resolute. No changes needed for jammy.

Changelog-None.

I tried to run contrib/cl-repro.sh with this but now i get an error that it can't find the lowdown package (both noble and resolute). I think it's because the apt sources are not configured for universe where lowdown is located: https://packages.ubuntu.com/noble/lowdown

Can we just add universe? It works for me after doing this:

@ShahanaFarooqui I tried noble and resolute with

./tools/build-release.sh bin-Ubuntu-noble --force-version v26.06 --force-unclean --force-mtime 2026-06-04
./tools/build-release.sh bin-Ubuntu-resolute --force-version v26.06 --force-unclean --force-mtime 2026-06-04

and resolute worked fine for me. noble had some issues with some shasums which i updated in the fixup commit. Please let me know how to reproduce your resolute issue.

As it turns out, my AI and I took a little detour into hallucination land. I was simply running the wrong command for resolute 😅 . Thanks a lot for fixing it up!!! Squashed your fixup, as leftover fixup commit sometimes created issues for our Mac users.
