Clark Boylan df4f11393b Drop python 3.8 base image builds
Python 3.11 is coming up and running image builds for all the pythons
gets overwhelming fast. We end up with so many jobs that landing any one
change to our base images becomes difficult. To reduce the total count
we remove builds for 3.8 to make room for 3.11. Only a few things appear
to still be using the 3.8 images and their updates are all listed as
depends on below.
