### Godot version

4.0.2

### System information

Ubuntu 22.04.1 LTS

### Issue description

WorldBoundary2D tries to imitate a line in hessian normal form, since unlike the Plane variant, Godot doesn't have a Line variant. But the distance in the property spinbox is forced above 0.01px for no reason, as negative values work just fine and make sense in the context.

### Steps to reproduce

Create a WorldBoundary2D, see the distance property's input field.
