Update Docker images to python 3.10

This updates the grafyaml docker images to python 3.10. We do this
because 3.10 has been shown to be quicker than 3.8. Also, 3.11 is coming
up soon and moving off of 3.8 will allow us to remove those images
before adding 3.11 which keeps to image build count to a more reasonable
number.

We update the voluptuous version to add python 3.10 support. In
particular collections.Mapping moved to collections.abc.Mapping.
