fix(eslint-plugin-specs): removes unnecessary `ENOENT` error check (#36448)

Summary:
```javascript
      // workaround https://github.com/nodejs/node/issues/31481
      // todo: remove the ENOENT error check when we drop node.js 13 support
      case 'ENOENT':
      case 'EACCES':
```

Well, there was a TODO comment asking to remove `ENOENT` error check when react native drop nodejs 13 support since nodejs 14 has fixed the bug that motivated this check. Now react native minimum nodejs version supported is nodejs 14, so this check is not needed anymore.
