Move grafyaml to Bookworm and python 3.11

This updates python testing to py311, adjusts the trove identifiers to
match, and switches the docker file to using python3.11 on Bookworm.

The motivation behind this is once OpenDev has updated all services to
Bookworm and python3.11 the old bullseye images and images for older
python versions can be cleaned up.
