Greptile Summary

This PR adds the zip and unzip command-line utilities to the PhysicsNeMo Docker image. The change modifies the builder stage's apt-get install command to include these two compression tools alongside existing dependencies (git-lfs, graphviz, libgl1). Since the builder stage serves as the base for all downstream stages (ci, deploy, docs), these utilities become available throughout the container lifecycle. This is a practical addition for a scientific computing framework that likely handles compressed datasets and archives, enabling users to work with .zip files directly within the containerized environment without requiring additional manual installation steps.
