Replace urllib with requests to Restrict Unsafe Protocol Handling

[Tanmaykaturi]

Describe your change:

• Fix a bug or typo in an existing algorithm?

"Fixes #ISSUE-NUMBER".
This PR replaces the use of urllib.request.urlopen() with requests.get() for fetching the dataset URL.
While the current URL is hardcoded and safe, urllib supports additional protocols such as file:// and ftp://. If the URL ever becomes dynamic or user-controlled in the future, this could introduce a risk of unintended local file access or data exposure.The requests library only allows http:// and https:// by default, which helps prevent entire classes of protocol-based vulnerabilities. This change improves security posture through defense-in-depth while preserving identical functionality for valid web requests.This update is a proactive, preventive security improvement aligned with best practices.
