Feat: add default reown appkit provider

[sirpy]

Add a component for a default appkit provider with our default settings
use projectid from env variables
add support for chains: ethereum, base, xdc, fuse and celo
then use this component in ai-credits-widget app instead of the injected provider
https://github.com/GoodDollar/GoodWidget/blob/main/apps/ai-credits-web/src/App.tsx
make sure latest appkit is added
add a playwright test to ensure it is working

import { AppKitProvider } from '@reown/appkit/react'

function App() {
  return (
    <AppKitProvider
      projectId="YOUR_PROJECT_ID"
      networks={
        [
          /* Your Networks */
        ]
      }
    >
      {/* Your App */}
    </AppKitProvider>
  )
}
