Breaking: Update peer dependencies for Vite 4

[IanVS]

Fixes #526

This updates the peer dependencies for vite and vite plugins, and also updates @joshwooding/vite-plugin-react-docgen-typescript to a version that makes TypeScript an optional dependency, to avoid peer dependency warnings for non-typescript projects.

Finally, I added a bit of a script to run yarn install in each of the example projects because I got really tired of doing that manually. ;)

FWIW, this will require a bump of this project to 0.3.0 when released. We did something similar for 0.1 to 0.2, without much trouble.

Hi!

It's missing to update the dependency @vitejs/plugin-react to v3.0 or higher.
Current version is using vite 3.

Hi @sfe-efficy, this was a breaking change that requires Vite 4. If you are using Vite 3, you'll need to install @storybook/[email protected].

I opened an issue, I guess it's better
