Bug description

When trying to use the BxGymActSpace on environment where not all actions are possible it raises an error (all actions
are illegal)

How to reproduce

Just run the code below:

import unittest
import warnings

import grid2op
from grid2op.Rules.AlwaysLegal import AlwaysLegal
from grid2op.gym_compat import GymEnv
from grid2op.gym_compat import BoxGymActSpace


class Issue283Tester(unittest.TestCase):
    def setUp(self):
        with warnings.catch_warnings():
            warnings.filterwarnings("ignore")
            self.env = grid2op.make("educ_case14_storage", test=True, gamerules_class=AlwaysLegal)
            self.env_gym = GymEnv(self.env)
    
        self.env_gym.action_space.close()
        self.env_gym.action_space = BoxGymActSpace(self.env.action_space)
        self.env_gym.seed(0)

    def tearDown(self):
        self.env.close()
        self.env_gym.close()

    def test_can_make(self):
        """test that the opponent state is correctly copied"""
        gym_act = self.env_gym.action_space.sample()
        gym_act[:self.env.n_line] = 0.  # do not change line status ! (otherwise it diverges)
        act = self.env_gym.action_space.from_gym(gym_act)
        obs, reward, done, info = self.env.step(act)
        assert len(info["exception"]) == 0, f"{info['exception'] = }"

Current output

grid2op.Exceptions.IllegalActionExceptions.IllegalAction: Grid2OpException IllegalAction "Impossible to perform curtailment action with this action type."
