Collect Metrics for Docker Versions

[kbukum1]

What are you trying to accomplish?

This pull request focuses on two main changes:

1. Collecting metrics for Docker versions to better track and analyze dependency updates.
2. Refactoring the code by moving all string literals into constants for improved maintainability and consistency.

Anything you want to highlight for special attention from reviewers?

• Ensure that the metrics collection logic correctly captures and reports Docker version data.
• Validate that all string literals have been moved into constants without introducing errors or inconsistencies.

How will you know you've accomplished your goal?
