Description by Korbit AI

What change is being made?

Update the Dockerfile to fix image-level vulnerabilities by upgrading packages using apk upgrade, adding missing no-cache flags, consolidating package additions, and cleaning up cache after installation.

Why are these changes being made?

The changes address security vulnerabilities present in the Docker image by ensuring that all installed packages are updated to their latest versions and unnecessary caches are removed to reduce the attack surface and overall image size. This approach follows best practices for building secure and efficient Docker images.
