This is done for a number of reasons. First it will allow us to update
the python version used in the images as we can have a 3.10 builder and
base images (but not a 3.10 openjdk:11 image). Second it will allow us
to easily switch to openjdk 17 by simply updating the package we install
and some paths for the jdk location.
The goal here is to have more control over the images so that we can do
things like change python and java versions when we want to.
