Although ESLint excludes node_modules/ by default when actually linting, the overrides rule for TypeScript does scan the dependencies when looking for TypeScript files (using files: '**/*.ts?(x)'). That means that, even if the linted code contains no TypeScript at all, the override triggers. An attempt to load @typescript-eslint/parser is made, which fails due to TypeScript not being installed.
This PR adds an explicit top-level ignore for node_modules/, which appears to prevent this (tested with a vanilla app made using npx create-react-app@latest).
Fixes #8745 (closed), #8936.
