nightly: bump Ubuntu release from plucky/noble to resolute

Plucky (25.04) reached EOL on 2026-01-25 and resolute (26.04 LTS)
just promoted to `supported` in armbian/build's config/distributions.

Two swaps, both scoped to nightly targets:

- targets-release-nightly.manual: minimal-cli-stable-ubuntu-cloud
  flips RELEASE plucky -> resolute (the target is labelled
  "Ubuntu stable" but was pinned to an interim release).
- generate_targets.py: generate_nightly_yaml() now emits
  nightly-resolute-{gnome,xfce,riscv64-xfce,minimal} instead of
  the noble-named variants. Target keys, RELEASE values, block
  comments, the function docstring, and the trailing loongarch
  note are all updated.

Stable and community targets in generate_targets.py stay on noble —
this change is nightly-only per the request. Once resolute is
confirmed good on the nightly channel, the same swap can be
repeated for stable/community in a follow-up.
