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?

              <Suspense fallback={'[loading first]'}>
                firststart
                <AsyncText text={'first suspended'} />
                firstend
              </Suspense>
              <Suspense fallback={'[loading second]'}>
                secondstart
                <b>
                  <AsyncText text={'second suspended'} />
                </b>
              </Suspense>
              end
            </div>
          </Suspense>
        );
