Refactor image pulling logic to support different pull commands

- Updated the image pulling mechanism to conditionally format the pull command based on the command type (e.g., crictl).
- Improved code readability by reducing redundancy in command construction.

This change enhances flexibility in handling image pulls across different environments.
