Containerize Boltz, add CI workflows

Add docker files and github workflows for automated docker image builds.
Builds images with tags: main (python:3.10-slim), cuda12-1, and
cuda12-4. Commit summaries containing "[no-ci]" will skip builds, and CI
only runs with changes to core files. Have a good day.
