Render mode not implemented for parking-v0

[araffin]

To reproduce (with gym 0.26+ and highway env 1.7.0):

import highway_env
env = gym.make("parking-v0", render_mode="human")

File ~/miniconda3/envs/py31/lib/python3.11/site-packages/gym/envs/registration.py:640, in make(id, max_episode_steps, autoreset, apply_api_compatibility, disable_env_checker, **kwargs)
    637     render_mode = None
    639 try:
--> 640     env = env_creator(**_kwargs)
    641 except TypeError as e:
    642     if (
    643         str(e).find("got an unexpected keyword argument 'render_mode'") >= 0
    644         and apply_human_rendering
    645     ):

TypeError: ParkingEnv.__init__() got an unexpected keyword argument 'render_mode'

Note that it works for the other envs.
Oh, and you need to upgrade as "racetrack-v0" breaks with numpy 1.24:

File ~/miniconda3/envs/py31/lib/python3.11/site-packages/highway_env/envs/common/observation.py:270, in OccupancyGridObservation.__init__(self, env, features, grid_size, grid_step, features_range, absolute, align_to_vehicle_axes, clip, as_image, **kwargs)
    268 self.grid_size = np.array(grid_size) if grid_size is not None else np.array(self.GRID_SIZE)
    269 self.grid_step = np.array(grid_step) if grid_step is not None else np.array(self.GRID_STEP)
--> 270 grid_shape = np.asarray(np.floor((self.grid_size[:, 1] - self.grid_size[:, 0]) / self.grid_step), dtype=np.int)
    271 self.grid = np.zeros((len(self.features), *grid_shape))
    272 self.features_range = features_range

File ~/miniconda3/envs/py31/lib/python3.11/site-packages/numpy/__init__.py:284, in __getattr__(attr)
    281     from .testing import Tester
    282     return Tester
--> 284 raise AttributeError("module {!r} has no attribute "
    285                      "{!r}".format(__name__, attr))

AttributeError: module 'numpy' has no attribute 'int'

Thanks a lot for the detailed bug report! This is now fixed at head

Edit: released v1.7.1
