restic/ana-ml2: exclude parakeet HF cache volume

First backup run pulled in 9 GB due to /var/lib/docker/volumes/
parakeet_parakeet_cache — Parakeet is the only AI stack on ana-ml2
using a docker named volume for its HF model cache (kokoro, vibevoice,
comfyui, llama-swap, vllm-qwen3 all bind-mount from /tank which is
already outside source paths).

Excluding brings expected snapshot size back to ~100-300 MB.
