Docker compose error

TL;DR

cd docker && cp.env.example.env && docker compose up fails: the jawn/valhalla build context in docker-compose.yml doesn't match the repo's directory layout (missing shared directory context), plus unset MINIO env vars.

Steps

1. Community workaround (koshyviv): in ./docker/docker-compose.yml change the jawn build context to .. with dockerfile: valhalla/dockerfile, and in ./valhalla/dockerfile build with the parent directory as context (COPY ./valhalla/jawn/... and ./shared ... with the corrected paths). Maintainer chitalian confirmed and linked PR #3195 as the repo-side fix.
