test(sample): add FeedbackWidgetProvider to React Native sample app

Without FeedbackWidgetProvider rendered in the tree, componentDidMount
never fires, startShakeListener is never called, and the native swizzle
is never set up — so shake-to-report has no effect despite
enableShakeToReport: true being configured on the integration.
