Extend e2e tests

[RobinBomkamp]

The e2e tests should be extended. Currently it is testing only a single page with a vite host and vite, webpack and rspack remote.

I think there should be tests for different combinations of frameworks.
For example:

• Vue host + Svelte remote
• Svelte host + React remote
• React host + Vue remote

What do you think about that? I would also like to create these tests.

I've been thinking the same thing for a few weeks, but I'd like to change the point of view.
clone of projects via GH action that use and MF vite and launch their tests with the latest build.
this would ensure safety at every release.
Do you like the idea? would you like to try to create a GH action?

• MF Vite build
• clone external repo
• using the new MF vite build in the cloned code
• launch the cloned repository tests

you can use the examples we have in the README if you want
