Update log_example_reports.py

[DhruvKadam-git]

1. Added logging: Imported the logging module and set up a logger in the main function. This allows for better error tracking and debugging.

2. Improved file reading: Used a with statement to ensure the file is properly closed after reading. Also added error handling to catch and log any issues when reading the file.

3. Error handling for Slack SDK import: Added a try-except block to handle cases where the slack_sdk might not be installed.

4. Enhanced Slack message sending: Added error handling and logging for the Slack message sending process. This will help identify any issues with the Slack integration.
