Fix key bindings in 3d_gizmos example after camera controller (bevyen…

…gine#14812)

# Objective

Fixes bevyengine#14811

## Solution

- Switch `D` to `T`: `T` for "on top of"
- Switch `A` to `B`: `B` in "AABB", or "boxes"

## Testing

- Ran the example locally
- Checked the key bindings that the camera controller uses and made sure
we're not using them in the 3d_gizmos example anymore
