fix: ignore node/ directory in ESLint config

The `node/` directory contains a checkout of the Node.js source tree
whose own `eslint.config.mjs` references files that don't exist in
this repo (e.g. `benchmark/eslint.config_partial.mjs`). Add it to the
`ignores` list so `node --run lint` doesn't fail.
