Updated internal dep from Rollbar Apple SDK 1.x to 2.3.4.

[matux]

Description of the change

The Flutter SDK also runs the Rollbar Apple SDK internally in-order to catch crashes and errors that may happen in native code. We were using a very old version of the Rollbar Apple SDK which was causing compilation issues on Apple Silicon arm64.

This should not only take care of that issue, but improve the ability for users to catch errors and fix them while using the Flutter SDK.
