Xcode 15.2 Compile Errors: `attachmentAnchor` argument of `ornament` modifier now demands UnitPoint instead of Alignment

## Error description

In Xcode15.2, compile errors occur because `attachmentAnchor` argument of [`ornament` modifier](https://developer.apple.com/documentation/SwiftUI/View/ornament(visibility:attachmentAnchor:contentAlignment:ornament:)) now demands [UnitPoint](https://developer.apple.com/documentation/swiftui/unitpoint) instead of [Alignment](https://developer.apple.com/documentation/swiftui/alignment):

```
Cannot convert value of type `Alignment` to expected argument type 'UnitPoint'

Extraneous argument label 'alignment:' in call Remove 'alignment: '
```

## Screenshots

## Solution

Change Alignment with UnitPoint, like creating a new computed property `unitPoint` in the struct 'OrnamentAlignment'
