feat: streamline vinext + module-federation/vite

[gioboa]

Hi, congratulations for this amazing project. 👏

I created an example using @module-federation/vite, and everything works fine. Here is the code

However, I ran into the problem of having multiple react instances at runtime.
I found a workaround, the idea is to have a method that exposes the host react instance for consumers.

I took inspiration from the Nuxt API useNuxtApp.
With Nuxt, for example, you can use const { $pinia } = useNuxtApp(); to retrieve the unique state instance and use that one inside multiple applications.

Would you mind thinking about a public API to support this scenario?

Woah! That is super cool. Yeah I am definitely open to it. Feel free to suggest what this should look like
