Updating notebooks, removing errors and checking packages compatibility

Notebooks design_variables.ipynb and drivers.ipynb use the Full-Factorial approach, requiring the openmdao and pyDOE2 packages, which are compatible with Python 3.8 and 3.9. (If using a higher Python version, these packages cannot be installed) A comment has been added to note this requirement, and a cell was added to install these packages if they are not already installed. In the roads_and_cables.ipynb notebook, the aep_calculator module was removed because it does not exist and was not used in the notebook, only causing errors. In the wake_steering_and_loads.ipynb notebook, the surrogates_interface dependency was added to enable the import of the IEA34_130_1WT_Surrogate module from py_wake, which is utilized in the code.
