Remove Docker registry caching from GitHub Actions build workflow

[jfrench9]

Summary of Changes

This PR removes Docker registry caching from the GitHub Actions build workflow to simplify the build process. The change removes 3 lines from the workflow configuration file, streamlining the Docker build step by eliminating the registry cache mechanism.

Key Improvements

• Simplified Build Process: Removes complexity from the Docker build workflow by eliminating registry caching logic
• Reduced Configuration Overhead: Fewer configuration parameters to maintain in the CI/CD pipeline
• Cleaner Workflow: Streamlined GitHub Actions workflow with reduced dependencies on external caching mechanisms

Breaking Changes

None. This is an internal CI/CD optimization that does not affect the application functionality or API.

Testing Notes for Reviewers

• ✅ Verify that the GitHub Actions workflow still builds successfully without registry caching
• ✅ Check that build times are acceptable without the caching mechanism
• ✅ Confirm that the Docker image is still created correctly
• ✅ Monitor the first few builds after merge to ensure no regression in build stability

Browser Compatibility Considerations

No browser compatibility impact as this change only affects the CI/CD build process.

Additional Notes

While this change may result in slightly longer build times due to the removal of Docker layer caching, it eliminates potential cache-related build issues and reduces the complexity of the build pipeline maintenance.
