Description: Update the Containerfile for the prometheus to ensure it meets hermetic build requirements. This includes preventing external network calls during the build process and ensuring all dependencies are pre-declared.

Acceptance Criteria:

• Modify the Containerfile to ensure no external resources are fetched during the build.
• Ensure dependencies for the prometheus are explicitly declared within the repository and fetched before the build starts.
• Test the build pipeline to verify no external internet access is necessary for the build process.
