docs(annotate): add HF Jobs runner example for lerobot-annotate

A ready-to-run example of launching the annotation pipeline on a
Hugging Face job (h200x2) with two vllm replicas serving
Qwen3.6-35B-A3B-FP8. Lives next to other end-to-end recipes under
examples/.

+"""Launch ``lerobot-annotate`` on a Hugging Face job (vllm + Qwen3.6 MoE).
+
+Spawns one ``h200x2`` job that:
+
+  1. installs this branch of ``lerobot`` plus the annotation extras,
+  2. boots two vllm servers (one per GPU) with Qwen3.6-35B-A3B-FP8,
+  3. runs Module 1/2/3 across the dataset (per-camera VQA via PR 3471),
+  4. uploads the annotated dataset to ``--push_to_hub``.
+
+Usage:
+
+    HF_TOKEN=hf_... uv run python examples/annotation/run_hf_job.py
+
+Adjust ``CMD`` below to point at your own dataset / target hub repo.
