Dockerfile outdated (bookworm vs. bullseye)

[jangrewe]

I tried to build a container image from Dockerfile full, but it seems like the file was written when python:3 still used bullseye as the base. Now that python:3 uses bookworm, the build fails.

The fix:

FROM python:3-bullseye

Updating the Dockerfile to work with the bookworm version of python:3 would of course be prefered...
