Fix: Handle connection timeouts and resolve unhandled exception

[suyash469]

Summary

The scraper was crashing with an unhandled exception when a connection timeout occurred (e.g., Read timed out). Additionally, there was a logic error in repo_scraping_utils.py where response.status_code was accessed inside an except block where response was not defined.

Changes

• Refactored github_api_request in repofinder/scraping/repo_scraping_utils.py.
• Added proper try-except blocks to catch requests.exceptions.RequestException and other connection errors.
• Implemented a retry mechanism (max 3 retries) with a timeout increase to 30 seconds to handle unstable connections.
• Fixed indentation and variable scope issues preventing the script from running continuously.

Testing

• Ran the script locally; verified it now catches timeouts (logging them as warnings) instead of crashing the entire process.
