fix: add missing Python modules to Dockerfile

Pull Request

Proposed Changes

This change includes env.py and auth.py in the container image. These modules are currently missing, resulting in ModuleNotFoundError.

Note: This likely hasn't been reported before because action.yml still specifies the stale_repos:v1 image, so even when using later versions of this action, the image that's pulled is still stale_repos:v1. I also opened #325 to address that seperately.
