When using `window.onerror` in the bootstrap script that is hosted in a CDN the error message will show `"Script error."` instead of a proper error message. This is because of the [cross-origin](https://blog.sentry.io/2016/05/17/what-is-script-error/) script. To fix this issue a `crossorigin="anonymous"` attribute needs to be added in the script tag.

Currently, `bootstrapScripts` supports [`src` and `integrity`](https://github.com/facebook/react/blob/0fce6bb498357feb4465859912004b2e20fe7084/packages/react-dom-bindings/src/server/ReactDOMServerFormatConfig.js#L226) as configurations, should it also supports a `crossorigin` property?


console.error(
        'Internal React Error: React expected bootstrap script with src "%s" to not have been preloaded already. please file an issue',
        src,
      );
    }
  }
  const props: PreloadProps = {
    rel: 'preload',
    href: src,
    as: 'script',
    nonce,
    integrity,
  };
  const resource: PreloadResource = {
    type: 'preload',
    chunks: [],
    state: NoState,
    props,
  };
  resources.preloadsMap.set(key, resource);
  resources.explicitScriptPreloads.add(resource);
  pushLinkImpl(resource.chunks, props);
