IsValidated filed is always false on FormView

[MarkLFT]

Describe the bug
I am using a FormView and have used a binding to a bool ObservableProperty in the ViewModel to the IsValidated property. But in the ViewModel the value is always false, even when no warnings on the form.

To Reproduce
Steps to reproduce the behavior:

1. Create a Maui ContentView.
2. Assign the View to a ContentPage.
3. Assign the ViewModel to the ContentPage.
4. In the ViewModel create an observableproperty of type bool and name IsValidated.
5. In the ContextView create a FormView and set the IsValidated property to "{Binding IsValidated}"
6. Add a TextField to the form with validation for RequiredValidation.
7. On running the app, if the text field is empty, I see the Required warning, if the text field has content the warning disappears as expected. However in both case on clicking the Submit button, the property in the VM called IsValidating is always false.

Expected behavior
IsValidated property in the ViewModel should show true when there are no issues on the form.
