feat: Add option to list configuration values #9930

✓	✨ New feature

Description

working on adding new config-related commands (pylint --config-list and pylint --config-list-show-origin) to help users debug Pylint configuration issues more easily. These commands will display the current configuration values and their origins, similar to how git config list and git config list --show-origin work.

We've added the corresponding options in base_options.py and are defining custom callback actions in callback_actions.py to handle these commands, ensuring that users can retrieve and verify their Pylint configuration setup in a clear and structured way.

Closes #9930

Is there a chance this could be added to pylint-config. I never got round to fleshing that out, but this does seem like a feature that should live there instead of the main command.
