gtk::MessageDialog is deprecated in favor of gtk::AlertDialog

[pieterdd]

relm4's documentation contains an example that uses gtk::MessageDialog. This is deprecated as of gtk4-rs 4.10 in favor of gtk::AlertDialog. I haven't been able to figure out how to use it within a relm4::view yet, but for now instantiating dialogs from the update method suits my needs.

@pieterdd would you mind sharing how you instantiate dialogs from the update method?

I do it like this:

gtk::AlertDialog::builder()
    .modal(true)
    .message("Hello world")
    .detail("This is a test")
    .build()
    .show(Some(root));

where root: &Self::Root.
