Fix missing local_files_only in record/replay

[Cadene]

What this does

• Add --local-files-only for record/replay

How it was tested + How to checkout & try?

1. Recorded 2 episodes without pushing on the hub

python lerobot/scripts/control_robot.py record \
  --robot-path lerobot/configs/robot/so100.yaml \
  --fps 30 \
  --repo-id cadene/so100_5_lego_test \
  --num-episodes 2 \
  --warmup-time-s 5 \
  --episode-time-s 60 \
  --reset-time-s 30 \
  --single-task "Pick up the lego blocks and put them in the box on the right side of the robot." \
  --push-to-hub 0

2. Resumed recording and record 1 more episode:

python lerobot/scripts/control_robot.py record \
  --robot-path lerobot/configs/robot/so100.yaml \
  --fps 30 \
  --repo-id cadene/so100_5_lego_test \
  --num-episodes 1 \
  --warmup-time-s 1 \
  --episode-time-s 60 \
  --reset-time-s 30 \
  --single-task "Pick up the lego blocks and put them in the box on the right side of the robot." \
  --resume 1 \
  --local-files-only 1

3. Visualized the dataset offline.

python lerobot/scripts/visualize_dataset_html.py     \
--repo-id cadene/so100_5_lego_test     \
--local-files-only 1

Thanks for this fix!
Tests are failing, can you add this change in tests/test_control_robot.py::test_record_and_replay_and_policy?

- replay(robot, episode=0, fps=1, root=root, repo_id=repo_id, play_sounds=False)
+ replay(robot, episode=0, fps=1, root=root, repo_id=repo_id, play_sounds=False, local_files_only=True)

Also, end-to-end tests are failing but this is because they are downloading full datasets from the hub each time and we're capping out the github runners capacities. We should disable them until we fix this.
