Build: Simplify caching in CI, use npm ci

Our setup is pretty standard, so manual configuration of `actions/cache` is
an overkill. Relying on built-in `actions/node` caching will also resolve
differences between caching configurations for macOS/Linux vs. Windows.

Also, switch from `npm install` to `npm ci` in CI.
