PCA in a model pipeline

We just saw that legendary Pokemon tend to have higher stats overall. Let's see if we can add a classifier to our pipeline that detects legendary versus non-legendary Pokemon based on the principal components.

The data has been pre-loaded for you and split into training and tests datasets: X_train, X_test, y_train, y_test.

Same goes for all relevant packages and classes(Pipeline(), StandardScaler(), PCA(), RandomForestClassifier()).
