Update opengl_vectorized_mobject.py (#3790)

The "insert_n_curves_to_point_list" function requires the "points" argument to be a numpy array, since it calls the "get_bezier_tuples_from_points" function, which requires "points" to be a numpy array because it has the "return points.reshape((-1, nppc, 3))" statement. Ordinary lists do not have a "reshape" method.

So we need to convert "sp1" and "sp2" to numpy arrays before calling the "insert_n_curves_to_point_list" function.
