Refactor jsx_umami to use Vite

yash.rode → made their first commit to this issue’s fork.

I am following Migrate CRA to Vite, it is not completely working yet, but can someone verify if I am on the right track.

The Migrate CRA to Vite has some good info, but probably shouldn't be followed too closely. Reasons include

1. The Umami demo uses esbuild, not Create React App
2. We're not serving anything via JS, this is strictly building. Things like running dev should still update when files change while using non-minified code, but Drupal is already doing the serving - no "application running on port x" needed

If we refresh the page with current MR, we are getting Using the "css" tag in runtime is not supported. Make sure you have set up the Babel plugin correctly. this error, in the previous version where we were using esbuild

linaria({
      esbuildOptions: {
        jsx: 'automatic',
    },
})

this code in create-react.mjsfixed the same problem, what is the equivalent of this in vite.config.ts?

dev, build:react-dev and build:react all three scripts are running with vite now.
