TheZwiss 180228f2d1 ci: bump actions to Node 24 runtimes to clear deprecation warning (#8)
GitHub is deprecating the Node 20 runtime for JS actions; every run printed a
warning that actions/checkout@v4, actions/setup-node@v4 and pnpm/action-setup@v4
were being force-run on Node 24. Bump each to its first Node 24 major (v5) across
all workflows — the smallest jump that clears the warning, avoiding the extra
behavior changes in checkout v6/v7 (credential persistence, fork-PR blocking)
that don't apply here. Our checkout jobs use push/pull_request, not
pull_request_target/workflow_run, so none are affected regardless.

Also bump the GitHub Pages actions in deploy-pages.yml (configure-pages v5->v6,
upload-pages-artifact v3->v5, deploy-pages v4->v5), which were likewise on Node
20. Inputs are unchanged; pnpm still pinned to 10.34.3 via the version input and
the packageManager field.

name: Publish Container Image
# Builds and publishes the Backspace application image to the GitHub Container
# Registry (GHCR) as a multi-architecture (linux/amd64 + linux/arm64) image, so
# self-hosters — including weak/ARM boxes like a Raspberry Pi — can `docker pull`
# a prebuilt image instead of building the ~1.6 GB image locally (the Vite build
# OOMs small ARM hosts). install.sh and docker-compose.yml default to pulling
# this image, with a from-source build as the fallback.
#
# This is intentionally SEPARATE from the desktop-installer workflow
# (release.yml) — they share the `v*` tag trigger but build entirely different
# artifacts and must not be entangled.
