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?

      textCache.set(text, newRecord);
    } else if (record.status === 'pending') {
      const thenable = record.value;
      record.status = 'resolved';
      record.value = text;
      thenable.pings.forEach(t => t());
