run.sh forwards host environment through an explicit allowlist, and four variables the Docker Hub pages document were never on it, so setting them through the helper the docs recommend did nothing and printed no warning.
Adds JUPYTER_PORT, UNSLOTH_SKIP_NOTEBOOK_SYNC, UNSLOTH_SKIP_NOTEBOOK_REFRESH and UNSLOTH_SKIP_GPU_CHECK to the list, and a test that derives its cases from the variable tables in DOCKERHUB.md and DOCKERHUB-ROCM.md so a documented option that stops being forwarded fails the suite.
Every variable in both tables now reaches the container. Same class of bug as #11109.
