Add KNN Regression Model

[Aditi22Bansal]

I'm creating a K-Nearest Neighbors (KNN) regression model using a dataset. I'm following these steps:

Loading and exploring the dataset.
Preprocessing the data.
Splitting the data into training and testing sets.
Building and training the KNN regression model.
Evaluating the model.
Hyperparameter Tuning: Using GridSearchCV to find the best n_neighbors value.
