feat(ansible): add VAD model download configuration (#6557)

* feat(ansible): add VAD model download configuration

Add Ansible tasks to download VAD CARLA Tiny model files:
- vad-carla-tiny_backbone.onnx
- vad-carla-tiny_head.onnx
- vad-carla-tiny_head_no_prev.onnx
- vad-carla-tiny.param.json

Models are downloaded to autoware_data/vad/ directory with SHA256 checksums for verification.

* feat(ansible): add version directory for VAD model downloads

Create v0.1 subdirectory for VAD models to support version management.
This enables Ansible to properly handle model updates without
overwriting existing model versions.

* fix(ansible): update checksum for VAD model param file

Update checksum for vad-carla-tiny.param.json to match the current
file available on the server. The file content was updated upstream,
causing the previous checksum validation to fail.
