#290 Regression causing notebook builds to fail to function

[ryanolee]

What

#290 Causes a regression in trying to run the notebook docker container. Given the execution fails to run in shell mode.

How

Given the dask notebook fails to start due to single quotes being used in the exec format. Has not cropped up as a problem yet due to latest build version being behind this change.

Minimal Complete Verifiable Example:

docker build --build-arg PYTHON_VERSION="3.12"  --tag notebook/docker-stacks-foundation:lab https://github.com/jupyter/docker-stacks.git\#main:images/docker-stacks-foundation && docker build --build-arg base="notebook" --build-arg release="2024.9.1" --build-arg py_version="3.12" --tag nb-test ./notebook && docker run --rm nb-test
