Continuous actions in PettingZoo API

[AmineAndam04]

Describe the bug in the the _update_action_spaces method of the UnityPettingzooBaseEnv class, you force the actions to be of int32 and in the [-1,1] range (see the code below). This constraint doesn't apply to all scenarios

act_spec.continuous_size > 0:
                    c_space = spaces.Box(
                        -1, 1, (act_spec.continuous_size,), dtype=np.int32
                    )

It makes more sense to use the same logic as in _update_observation_spaces.

obs_spaces = tuple(
                    spaces.Box(
                        low=-np.float32(np.inf),
                        high=np.float32(np.inf),
                        shape=spec.shape,
                        dtype=np.float32,
                    )

I'm aware that this issue was raised previously, but it is still present.

Console logs / stack traces The action to send is
