PySpark Function - exists

Start by creating a SparkSession, the foundation for all PySpark operations.
Next, define a dataset with an array column representing scores for each user.
Convert the dataset into a PySpark DataFrame for processing.
Use the exists function to check if any element in the 'scores' array satisfies the condition: score greater than 20.
Add a new column, 'has_high_score', indicating if the condition is true for any element.
Display the results to see which users have at least one score greater than 20.
Finally, stop the SparkSession to clean up resources.
