[Minor] Documentation Fix for Enabling the parameter output_original_output

Description

The IntervenableModel class requires the output_original_output boolean flag to be enabled for the code to function as expected. Not passing this parameter in the Jupyter notebook while intervening on ResNet models results in an empty dictionary for original outputs. Consequently, attempting to compute the difference between the intervened output and the original output raises the following error:

AttributeError: 'NoneType' object has no attribute 'logits'

Testing Done

The code was tested by including the parameter output_original_output=True. This change allowed for the correct computation of outputs without errors and the html build was verified accordingly.

This could however be changed to making the default value set to True when defining these functions in the intervenable_base module but these might be broader design choices. The same changes could possible result in erroring out in other blocks for different model architecture if the difference is computed but I haven't tested that.
