PoC: Vite as peerDependency

[JReinhold]

DO NOT MERGE

This is a PoC on making Vite and the Vite renderer plugins peer dependencies.

It works with Vue and Svelte, but React still breaks with stories in MDX (but plain MDX is fine).

This PR allows both Vite 3 and 4 (except for the SvelteKit framework), we still haven't decided if we want to only support Vite 4 at this point.
I've tested for all three frameworks that it works both when the user supplies Vite 3 and 4 (and matching plugins). Vite 3 + React Plugin 2 makes the stories in MDX work again, as expected.

To do

If we decide this is the path forward

• The CLI generator should add the Vite dependency and any needed plugins if they're not already there - similar to what we do with react and react-dom. This is a bit more complex though, as it differs between frameworks
• Fix MDX transpilation with @vitejs/plugin-react@^3.0.0.
