End to End Project - Bikes Assessment - Basic - Fine-Tuning the Selected Model - Defining GridSearchCV

Let us instantiate the GridSearchCV class by passing to it the following:

1. The selected model
2. The param_grid list (with hyperparameters combinations) that we created in the previous step
3. Cross-validation parameter cv parameter with value 5 (cv=5)
4. Scoring parameter with value as neg_mean_squared_error

Store this instance in grid_search variable.
