Issue:
What I did
This incorporates storybookjs/mdx2-csf#30 into the vite builder, removing the use of the vite react-plugin, freeing us to support vite 3 and 4!
Note: we'll want to update the version of
mdx2-csf
once the referenced PR is merged / released.How to test
I tested this out by creating a react sandbox, and testing both build and dev. HMR even seems to work in dev!
