Description: Modify the Containerfile for the korrel8r component to ensure it supports hermetic builds. The Containerfile should be updated to prevent fetching dependencies from external sources during the build and ensure all necessary resources are included.

Acceptance Criteria:

• Add prefetching steps for dependencies required by korrel8r.
• Modify the Containerfile to remove any external network access during the build process.
• Ensure that all dependencies are declared in the build definition (e.g., within the Git repository).
• Verify the build runs successfully without network access, pulling all dependencies before the build starts.
