Victoria Ashworth ecad29a177 Change element to wait for in AppExtensionTests testAppExtensionLaunching (flutter/engine#53358)
Instead of waiting for the first cell in the share sheet to appear, wait for the first cell matching the predicate to appear. It seems that on macOS 14 it [occasionally doesn't find any matches](https://github.com/flutter/flutter/issues/150117#issuecomment-2163493564), presumably a race condition - so this will wait up to 10 seconds for the desired elements to appear.

Attempting to fix https://github.com/flutter/flutter/issues/150117. I wasn't able to recreate locally and it only happens flakily in CI so hard to guarantee it will fix.
