code refactoring

[jokoyoski]

The list comprehension is used to directly create a list of dictionaries.
Each dictionary in the list has a single key-value pair where the key is "title" and the value is an item from the suggestion_titles list.
This refactoring simplifies the code by using a more concise and Pythonic approach to achieve the same result. The explicit loop and the creation of an empty dictionary (suggestion_dict) in each iteration are eliminated, resulting in improved readability and efficiency.
