Refactor Event wait() method for simplified code

[eval-exec]

This pull request refactors the wait() method of the Event struct to simplify the code and improve readability.

In the original implementation, the method used a loop to check for receiver updates by cloning the receiver and invoking receiver.changed().await.unwrap() within the loop. However, this can be simplified by directly invoking self.receiver.clone().changed().await.unwrap() in a single line.

The refactored code eliminates the need for the loop and makes the intention of waiting for receiver changes clearer. It reduces unnecessary code complexity while maintaining the functionality of the wait() method.

Are you aware that those changes are only for a test, not for the actual library?

Certainly, only integration test need Event struct.

Is there something wrong with the existing implementation? Especially as your rework now isn't compatible with repeated wait calls any more ...

The failing lint in the CI isn't your mistake, btw, it seems that clippy added a new check.
