feat(docker): add per-benchmark evaluation containers

Add Dockerfile.benchmark (parameterized via ARG BENCHMARK), a
docker-compose.benchmark.yml with services for libero, libero_plus,
robomme, and robocasa, and a smoke_test_benchmark.sh that verifies
imports and CLI entry-points in each container.

Also add the missing `robocasa` optional dep group to pyproject.toml
(the docs already referenced `pip install ".[robocasa]"` but the group
was not defined).

Build a specific benchmark image:
  docker build --build-arg BENCHMARK=robomme \
    -f docker/Dockerfile.benchmark -t lerobot-benchmark-robomme .

Build all via compose:
  docker compose -f docker/docker-compose.benchmark.yml build

Smoke-test inside a container:
  docker compose -f docker/docker-compose.benchmark.yml run --rm robomme \
    bash docker/smoke_test_benchmark.sh
