Switch base Docker image from python:3.9.6 to a current alpine image

[ameliav]

💡 Summary

Switch base Docker image from python:3.9.6 to a current alpine image (e.g. python:3.10.0-alpine) and with working Python package installations

Motivation and context

The pca-report-library Dockerfile should be updated to Alpine to match the skeleton-docker. A direct update to Alpine will not work as there are some Python libraries such as matplotlib that are not directly compatible.

Implementation notes

According to the below links, there are Linux dependencies that need to be installed and also headers missing where the packages are looking for them.

Acceptance criteria

• A single apk command should be used to install wget, the tex packages, and other packages
• List of packages is alphabetized
• Python packages are properly installed and working
