Stencil React Testing

This is a monorepo for testing and reproducing bugs related to Stencil's React integration. packages/react-library was created following Stencil's React Integration documentation. There are two apps, both of which have caused us problems in the past:

1. apps/vite with Vitetest, which uses JSDOM under the hood.
2. apps/nextjs with prerendering setup to use GetStaticProps instead of a custom server. See Stencil's Hydrate App documentation for more information.
