[BUG] Issue with reset method of Boxohack environment due to Gymnasium API change

[just-oliver]

🐛 Bug

<The ported Boxohack environment currently doesn't work with the Gymnasium API>

To Reproduce

Steps to reproduce the behavior:

1. env = gym.make("MiniHack-Boxoban-Unfiltered-v0")
2. env.reset()

Expected behavior

I expect for reset() to cause the the environment to reset without throwing this error related to unexpected seed.

Environment

Please copy and paste the output from running our
environment collection script
(or fill out the checklist below manually).

You can get the script and run it with:

# with repo already installed
$ python -m minihack.scripts.collect_env

# or instead pull it from github
wget https://raw.githubusercontent.com/facebookresearch/minihack/main/minihack/scripts/collect_env.py
# For security purposes, please check the contents of collect_env.py before running it.
python collect_env.py
