Description

Description of bug / unexpected behavior

I'm trying to change the base configurations for LinearTransformationScene, but I get an error. This was not the case when I was using the previous version of Manim a few days ago

Expected behavior

I was hoping to change the configs without getting an error

How to reproduce the issue

Following is some example code taken from the docs. The first line was to get it to run in Google Colab (as described in the tutorials section)

 %%manim LinearTransformationSceneExample
 
 class LinearTransformationSceneExample(LinearTransformationScene):
            def __init__(self):
                LinearTransformationScene.__init__(
                    self,
                    show_coordinates=True,
                    leave_ghost_vectors=True,
                )

            def construct(self):
                matrix = [[1, 1], [0, 1]]
                self.apply_matrix(matrix)
                self.wait()

Logs

TypeError: __init__() got an unexpected keyword argument 'renderer'

Research direction
Investigate the init method of LinearTransformationScene and its parent class Scene to understand why the 'renderer' parameter is being passed unexpectedly. Check recent commits that may have changed the initialization process. Replicate the error in Google Colab using the provided code snippet, then identify the necessary changes to ensure compatibility with the current version of Manim.
