Expo: Use Metro bundler for the web target example

[jay-jlm]

Which project is this feature idea for?

Turborepo

Describe the feature you'd like to request

Currently running npx create-turbo@latest -e with-react-native-web I end up with Expo 49 and "@expo/webpack-config" as dependencies in package.json

Describe the solution you'd like

Expo SDK 50 is moving away from webpack and adopting Metro as the preferred bundler for the web target.
The expo web target example should be updated to include these recent developments.
Migration information is provided here: https://docs.expo.dev/router/migrate/from-expo-webpack/

Describe alternatives you've considered

Update current example or provide a new one with the updated configuration.

I'll have to admit that I don't have much expertise with react-native's ecosystem.

If you (or anyone!) can create a PR for this, I'd be happy to review!

[jay-jlm]

Thanks @anthonyshew , I just edited the issue to include information on how to migrate to their new system.
I haven't had the need to use the web target before but I will be happy to provide a PR if end up working on this feature in the coming days.
