Add URL Logging for Visited Pages

[Cgarg9]

Description

Currently, the AI Web Scraper (/GenAI/AiWebScraper) does not keep a log of the URLs it visits while retrieving information. To enhance verifiability and allow for a review of the sources, implement a feature that logs all visited URLs in a separate file.

Feature Requirements

• Save each visited URL in a .txt or .csv file with a timestamp.
• Ensure that duplicate URLs are not logged if they are visited more than once per session.
• Log file should be stored within a logs or data subfolder inside the GenAI/AiWebScraper directory.

Acceptance Criteria

• The feature successfully saves each unique URL visited during a session to the designated log file.
• The log file is easy to read and structured for future reference.
• Documentation for this feature is added to the README, explaining the purpose and file location for logged URLs.
