chore(dockerfile): remove unnecessary ubuntu docker base

[JonZeolla]

Contributor Comments

This removes the docker_base question, since we don't use Ubuntu as our parent image, we use the python images directly.

This will also have the side effect of speeding up CI/tests because we will have 2 fewer combinations to test generation.
