Describe the bug

I would expect changing a method to async in a migrated controller to not cause it to be treated as not migrated in the upgrade assistant endpoints dashboard

To Reproduce

Migrate a controller from a .net framework 4.8.1 to a NET 8 mvc app.

Change the index method from public ActionResult Index() to public async Task<IActionResult> Index().

Go to the upgrade assistant dashboard and look at the endpoint explorer. The method is shown as not migrated.

Exceptions (if any)
