### Godot version

v4.0.beta13.mono.official [caacade56]

### System information

Ubuntu 22.10

### Issue description

Small issue, but according to the documentation you can set the `dof_blur_near_transition` and `dof_blur_far_transition` practical camera attributes to [negative values](https://docs.godotengine.org/en/latest/classes/class_cameraattributespractical.html#class-cameraattributespractical-property-dof-blur-far-distance), but the editor / property hints only lets you set it to 0.01 and no lower, so you have to set the value in code.

### Steps to reproduce

1. Add a camera
2. Add practical camera attributes
3. Enable Near or Far DOF
4. Try to set the Transition to a negative value
