PhysicsTestMotionResult3D funcs say that their default param index '0' is the deepest collision, but its the earliest

**Your Godot version:** Godot 4.4.1

**Issue description:**
All method descriptions that return collision query results say **"(the deepest collision by default)"** referring to the default index parameter '0'.

But inspecting the source code it looks like **is the opposing** (assuming that "deepest" means "farthest").
Index 0 really returns the "closest / earliest" collision.

That makes sense because in most cases what is wanted is to know the shortest safe fraction before any collision happens.
