ci(pages): opt the Pages actions into Node 24

The deploy run warns that configure-pages@v5, upload-pages-artifact@v3,
and deploy-pages@v4 still run on Node.js 20 — which GitHub forces to
Node 24 on 2026-06-02 and removes on 2026-09-16. No newer majors move
them to Node 24 yet, so set FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true at
the workflow level (GitHub's documented opt-in). Silences the warning
now; a no-op once Node 24 is the default.
