chore(deps): bump Node from v20.11.0 to v22.12.0 for Vite 8 (unblocks #86)

Vite 8 (pulled in by PR #86's vite group bump) raised its engine
requirement to ^20.19.0 || >=22.12.0. Our pinned v20.11.0 fails the
frontend-maven-plugin `npm run build` step immediately:

  SyntaxError: The requested module 'node:util' does not provide an
  export named 'styleText'

(rolldown, which Vite 8 uses, depends on `node:util.styleText` — only
in Node 20.18+/22.x). Pinning to v22.12.0 — the minimum v22 release
that satisfies Vite 8 — keeps us on a currently-supported LTS line and
unblocks dependabot's #86 vite group bump.
