Description
Given Dockerfile
FROM ubuntu:22.04
RUN apt-get update && apt-get install -y python3-cryptography
When I run
../.docker/scout/docker-scout cves --only-cve-id CVE-2023-50782 --locations scout-testing:latest
I get in the output:

Suggested fix: docker scout should map the egg-info directories to apt packages. If they have been installed via apt, they should not be detected as pypi installed packages.

Research direction
Reproduce the report with the shown Dockerfile and the docker-scout cves command, then trace how the reported egg-info paths are classified. Done means the apt-installed cryptography package is mapped to its Ubuntu package and is not reported as a PyPI package, while the scan still identifies applicable vulnerabilities.
