Fix Node.js driver CI build broken by @types/node drift (#2452) (#2541)

The Node.js driver CI (npm install -> npm run build -> tsc) failed with
parser errors in node_modules/@types/node/ffi.d.ts (TS1139/TS1005/TS1109/
TS1128). package-lock.json is gitignored, so CI resolves dependencies
purely from package.json. @types/node was only pulled transitively via a
wildcard range (@types/pg and jest depend on @types/node@*), so a fresh
install grabbed the latest (26.x). That version uses `const` type
parameters (a TypeScript 5.0 feature) in ffi.d.ts, which typescript@4.9
cannot parse. skipLibCheck does not suppress these parser-level errors.

The runtime Node version is unrelated: @types/node is resolved from the
npm dependency graph, not the Node.js runtime.

Fix:
- Add a bounded direct devDependency "@types/node": "^20.19.0" so a fresh
  install constrains the typings to the Node 20 LTS line, which is
  compatible with typescript@4.9 and keeps the toolchain consistent
  (eslint 7 / typescript-eslint 4 / TS 4.9 / Node 20 typings).
- Pin CI to Node 20 (setup-node@v4, node-version: 20) for reproducibility
  and to match the pinned typings; replaces the deprecated setup-node@v3
  and floating node-version: latest.

Verified: a clean, no-lockfile install (matching CI) now resolves
@types/node@20.19.43 and tsc builds successfully.
