…#42907)

Summary:
In a pnpm setup, `react-native config` fails to read `react-native/react-native.config.js` because `ws` was not installed:

```
% node --print 'require("react-native/react-native.config.js")'
node:internal/modules/cjs/loader:1137
  throw err;
  ^

Error: Cannot find module 'ws'
```
