Fix flipped faces on geometry nodes instances (v0.12.2)

Reverse face winding in _realize_instances() by swapping vertices[1]
and vertices[2] per triangle. loop_triangles.vertices internal order,
when fed to from_pydata() as a standalone mesh, produces inward-facing
normals. The swap ensures outward-facing normals that display correctly
after the Blender→Godot coordinate conversion pipeline.
