ThreeDScene's set_to_default_angled_camera_orientation method raises AttributeError #4472
Description
Description of bug / unexpected behavior
The set_to_default_angled_camera_orientation method of ThreeDScene raises an AttributeError when called because the class attribute default_camera_orientation_kwargs does not exist.
I believe that the problem comes from these lines:
manim/manim/scene/three_d_scene.py
Line 50 in 9528337
manim/manim/scene/three_d_scene.py
Line 431 in 9528337
The classes's __init__ method sets an attribute called self.default_angled_camera_orientation_kwargs, but the method tries to access an attribute called self.default_camera_orientation_kwargs.
Expected behavior
I expect that set_to_default_angled_camera_orientation should not raise an AttributeError.
I also expect that the keyword arguments such as phi and theta can be passed to this method because this is what is described in the documentation: https://docs.manim.community/en/stable/reference/manim.scene.three_d_scene.ThreeDScene.html#manim.scene.three_d_scene.ThreeDScene.set_to_default_angled_camera_orientation
How to reproduce the issue
See the code snippet below.
The line that raises the error is the very first call to set_to_default_angled_camera_orientation in the ThreeDScene's construct method.
The create_3d_crystal_lattice function is not important but included to make the code snippet run.

There is a telling comment in the source code that indicates that the programmer was aware that it was not clear where the attribute comes from:
