chore: update ESLint configuration and dependencies

- Removed `.eslintignore` file.
- Added `eslint.config.mjs` for ESLint configuration using the latest ESLint and TypeScript ESLint packages.
- Updated `package.json` and `package-lock.json` to use ESLint version 9.32.0 and added TypeScript ESLint as a dependency.
- Made minor type adjustments in `src/extract-react-intl/index.ts` for better type handling.
