Follow ups to bevy 0.16

bevy 0.16 support from https://github.com/dimforge/bevy_rapier/pull/642 left out a few important things:

- [x] bevy_mod_debugdump is targeting git, we should target the crate when it's released
- [ ] ambiguity detection is failing on a new ambiguity:
- a fix can be to add `.ambiguous_with(bevy::ui::ui_layout_system)` on `sync_simple_transforms` and `propagate_parent_transforms` ; but further analysis on why this happen and if we can do better would be appreciated.

Patch attempt for ambiguity

This is not enough because we're not sure if bevy ui is in the tree. We could fix it by adding a feature... 🤔 ; but I imagine we should make the propagation more clever...
