Updates the expected steps in the async function defined within `stepping_project.dart`. The Dart web team is updating the async semantics of DDC to bring them in line with the other backends. Currently, the DDC async semantics don't adhere to the Dart spec and this can lead to inconsistent and surprising results. However, the step-over operation doesn't work well yet with the new DDC async semantics. In the long run we intend to improve this but until then the debug stepper will have sporadic results that we can't model well with this test. When we are able to fix the stepper functionality, we will return this test to cover more of the async function being stepped over.
