Description

This PR removes CRA from examples, and add E2E testing for vite-babel-example

Closes #2411
unblocks #2430

I also added build and extract commands to the workflow, just to smoke test that they are working fine.

Important:

I also found that exports for /macro in both react and core was incorrect. Tests i created caught that. I fixed the issue in that PR as well.
