React 18 support

[mayank99]

CRA and create-vite ship with react 18, which our package.json is not compatible with, so npm install fails.

Action items

• Update peer deps react version in package.json ‼️
• Update react version in dev deps (will need to use sb 6.5 and testing lib 13)
• Update any components that are using old APIs (e.g. ReactDOM.render in Toaster.tsx)
• Check components in new StrictMode (e.g. in vite test app)

Won't this break old React versions?

I think we could keep backwards compatibility somehow. In this case, a simple fix could be to use createPortal.

I think we also should test on both React versions. But not sure whether just unit tests or visual tests too.
