Rather than specifying what OS should be used for the "base image" for CKAN we should target "Official Images" for python

eg: use:python:3.10-bookworm for Python 3.10 (latest) on Debian 12 (bookworm)
or python:3.10-slim for Python 3.10 (latest) on Debian 12 (slim bookworm)

Please note there are no Ubuntu distributions for Official DockerHub images for Python

Should we use specific release numbers ie: Python 3.10.14 rather than the latest for Python 3.10?
