We use Prism 8.1 and FlyoutPage is supported by this version. [Corresponding Pull request](https://github.com/PrismLibrary/Prism/pull/2403) Is the problem that FlyoutPage should also be added at this code position? [Prism.Plugin.Popups.Extensions.PageExtensions](https://github.com/dansiegel/Prism.Plugin.Popups/blob/48368a682a32a3f573d954dfb7207931e2a165c5/src/Prism.Plugin.Popups/Extensions/PageExtensions.cs#L28)

@davibittencourtome Wait for an update of PrismLibrary/Prism (current version 8.1.97) or dansiegel/Prism.Plugin.Popups (current version 8.0.76)? The Prism.Plugin.Popups alredy references 8.1.97 in its csproj. I think this issue should be reopened.

@dansiegel Any news on this?
