Update visualization/plot_image_gallery.py to solve an error in the object_detection_keras_cv.py in the keras-team/keras-io Project

Update visualization/plot_image_gallery.py
The guide has an issue when calling the visualization.plot_image_gallery function with its input being a list, it has to be of type array because it will be calling for the shape of it later in the function. The error occurred in the second code cell in the Beginner section, Ligne 155 in the object_detection_keras_cv.py file. This update should solve it.

Fixes #2015

Thank you @ImenMasmoudiEm! Have you tested this by any chance on the OD colab?

Thanks for the PR. Since the docstring says inputs should be a Tensor or Numpy Array, isn't this an incorrect use of the function in the tutorial?

[jbischof]

We are definitely planning to update the tutorial @sampathweb

[sampathweb]

Alternatively, can we raise a ValueError if the images is not the expected type of Tensor or ndarray?. Something like - isinstance(images, (tf.Tensor, np.ndarray))?

I have started initially with fixing the tutorial, it was suggested that we add it here.
My pull request is still pending for a change in the keras-io respitory.
