docs: update Worklets import forwarding setup

[eliotgevers]

Summary

Updates the React Native Worklets setup instructions to use importForwarding for remend when using react-native-worklets 0.10 or newer.

With the old workletizableModules option on newer Worklets versions, remend can be captured into the generated worklet closure as a remote function, which can cause this runtime error when StreamdownText mounts:

[Worklets] Tried to synchronously call a Remote Function.

The updated config forwards the remend import into the generated worklet so markdown preprocessing can still run on the worklet runtime. The docs also keep a short note for older Worklets versions that still use workletizableModules.

Closes #21.

Changes

• Replace workletizableModules: ['remend'] with importForwarding: { moduleNames: ['remend'] } in the setup examples
• Update both Expo and React Native CLI snippets
• Keep a compatibility note for older react-native-worklets versions

Test plan

• Docs-only change
• Verified the updated config in an Expo app using react-native-worklets 0.10.x
• Confirmed the generated worklet imports remend directly instead of capturing it in __closure
• Confirmed StreamdownText renders without the remote function error
