Let plugin define config "optimizeDeps" and "jsx"

[csr632]

Is your feature request related to a problem? Please describe.
Even if I am using vite-plugin-react, I still have to add jsx: "react" to my vite config.(The same goes with preact).

Furthermore, after the new vite-plugin-react is release, users still have to add optimizeDeps.include: ["react", "react-dom"] to their vite config.

Describe the solution you'd like

Let plugin (vite-plugin-react) help users to define "optimizeDeps" and "jsx" config.

This will let vite plugin system do more and let plugin users do less.

Describe alternatives you've considered
No.

Additional context

If you are open to this idea, I can help implementing this feature.

The plugin API in my mind is like this:

const myVitePlugin = {
   jsx: (prevJSX) => {
       if (prevJSX === undefined) return "react";
       return prevJSX;
   },
   optimizeDeps: (prevOptimizeDeps) => {
       if (!prevOptimizeDeps.inlude.find("react") && !prevOptimizeDeps.inlude.find("react-dom"))
         prevOptimizeDeps.inlude.push("react", "react-dom");
       return prevOptimizeDeps;
   }

}
