Attribution crashes because parentViewController is nil

Nobody has claimed this yet.

## Environment

- Xcode version: 14
- iOS version: latest
- Devices affected: all
- Maps SDK Version: 10.10.1

## Observed behavior and steps to reproduce

The attribution buttons tries to open the dialog on the `parentViewController` here: https://github.com/mapbox/mapbox-maps-ios/blob/192437b31f46860d10900e227dfc36ef30aaa130/Sources/MapboxMaps/Foundation/MapView%2BAttribution.swift#L6

However, this can be `nil` (SwiftUI, Ionic/cordova etc.) and leads to a crash.

## Expected behavior

To not crash 😇

## Additional links and references

A quick workaround for me is:
```swift
func viewControllerForPresenting(_ attributionDialogManager: AttributionDialogManager) -> UIViewController {
return (UIApplication.shared.delegate?.window??.rootViewController!)!
}
```

This could serve as a fallback in case the `parentViewController` is actually `nil`.

Start in Sources/MapboxMaps/Foundation/MapView+Attribution.swift at the attribution dialog presentation code linked in the issue. Trace how the presenting view controller is selected and verify the attribution action no longer crashes when parentViewController is nil; the issue's expected outcome is a safe behavior in that case.
