Migration from 1.x to 2.0.0

[superk589]

Using Gestalt 1.x, there are hundreds of files in my project have lines like this:

ThemeManager.default.apply(theme: Theme.self, to: self) { themeable, theme in
    ...
}

But in 2.0.0, ThemeManager.default.apply(...) is gone, is there an easy way to not change every file in my project to migrate to 2.0.0? (eg. write an extension to ThemeManager to get this method back)
