Ghost Nodes produce warnings because of UiTransform

## Bevy version and features

Bevy 0.17

## What you did

I've been migrating code from earlier version of Bevy that use ghost nodes.

## What went wrong

This now produces a slew of warnings, which it did not used to do:

```rust
2025-11-01T16:02:32.928747Z WARN bevy_ecs::hierarchy: warning[B0004]: Entity 97v0 with the GlobalTransform component has a parent (91v0) without GlobalTransform.
This will cause inconsistent behaviors! See: https://bevy.org/learn/errors/b0004
2025-11-01T16:02:32.928766Z WARN bevy_ecs::hierarchy: warning[B0004]: Entity 100v0 with the GlobalTransform component has a parent (99v0) without GlobalTransform.
This will cause inconsistent behaviors! See: https://bevy.org/learn/errors/b0004
2025-11-01T16:02:32.928890Z WARN bevy_ecs::hierarchy: warning[B0004]: Entity 119v0 with the GlobalTransform component has a parent (112v0) without GlobalTransform.
This will cause inconsistent behaviors! See: https://bevy.org/learn/errors/b0004
2025-11-01T16:02:32.928909Z WARN bevy_ecs::hierarchy: warning[B0004]: Entity 122v0 with the GlobalTransform component has a parent (121v0) without GlobalTransform.
```

The reason (as suggested on the Discord) is because of the replacement of `GlobalTransform` with `UiGlobalTransform`.
