Replace React Native Test Error Code Snippet with Sentry React Native Playground

[krystofwoldrich]

Instead of showing a copy-paste snipped for testing the React Native Error Reporting, the wizard could inject a component, which would show a simple fullscreen playground with a Throw an Error button, similar to the web wizards and the /sentry page.

This page could be a sub-export of the SDK @sentry/react-native/playground.

import { showSentryPlayground } from '@sentry/react-native/playground'

showSentryPlayground();
