[HANDS-ON BUG] unit 3: cannot load the correct trained model

# Describe the bug

I finished the training an agent with RL-Baselines3-Zoo. The model was saved to the path" /usr/local/lib/python3.12/dist-packages/rl_zoo3/logs//dqn/SpaceInvadersNoFrameskip-v4_1"

However, when I try to evaluate the trained agent by running these commands

!cd "/usr/local/lib/python3.12/dist-packages/rl_zoo3/"
!python -m rl_zoo3.enjoy --algo dqn --env SpaceInvadersNoFrameskip-v4 --no-render --n-timesteps 5000 --folder logs/

I got the following error "ValueError: No model found for dqn on SpaceInvadersNoFrameskip-v4, path: logs/dqn/SpaceInvadersNoFrameskip-v4.zip"

I did check the content in the path by using the command
!ls "/usr/local/lib/python3.12/dist-packages/rl_zoo3/logs/dqn/"
I realize that SpaceInvadersNoFrameskip-v4.zip was saved in the "/usr/local/lib/python3.12/dist-packages/rl_zoo3/logs/dqn/SpaceInvadersNoFrameskip" subdirectory, rather than the directory "/usr/local/lib/python3.12/dist-packages/rl_zoo3/logs/dqn/"

In this case, without changing train.py and enjoy.py, is there any other way to solve this bug?
