Beeware Template Project is Generated With Deprecated Code

[Gold-Vibes]

Describe the bug

Wanting to learn BeeWare for projects, I followed the tutorial on the website. Running the minimum code and testing out the features causes a deprecation warning in the terminal.

Steps to reproduce

1. Go to https://docs.beeware.org/en/latest/tutorial/tutorial-0.html
2. Follow all of the instructions on the page for a Windows environment
3. Click the bottom right arrow to go to Tutorial 1 - Your first app
4. Follow the steps until the section labeled Run the app in developer mode
5. Click on the running app's Help menu
6. Click on the About option
7. Check command line for messages

Expected behavior

No errors or warning as this is all completely new (downloaded a few days ago).
Template code should be up to date and use current conventions to help learners like me

Thanks for the report; it looks like we neglected to update the About menu on Winforms when we did the dialog refactor a few months back.

I'll migrate this to the Toga repository, as this is an issue with Toga, not the BeeWare website.

To clarify for anyone looking into this issue - the problem isn't with the generated template project; it's with Toga itself. The About menu (triggered by App.show_about_dialog() on each platform backend) on Winforms is still using the deprecated dialogs API. The implementation on Android is almost identical to the implementation on Winforms, but it has been updated.

The only complication may be whether the App.close_about_dialog() method on the Windows probe (in winforms/tests_backend/app.py) also need to be updated to change the mechanism for closing the about dialog.
