notebook broken due to Lightning API update: book1 14 cifar10_cnn_lightning.ipynb

Not your fault... Sadly, on google colab, the notebook is totally broken due to Lightning API update. Each cell has some kind of problems... Maybe fixable installing the old lightning, or update to the new one if it isn't to much work.
