Complete feature engineering pipeline

The recipes package is designed to encode multiple feature engineering steps into one object, making it easier to maintain data transformations in a machine learning workflow.

In this exercise, you will train a feature engineering pipeline to prepare the telecommunications data for modeling.

The telecom_df tibble, as well as your telecom_training and telecom_test datasets from the previous exercises, have been loaded into your workspace.
