Note: This function tries to construct the env from a string descriptor only using possibly installed RL env packages (such as gymnasium). These packages are no installation requirements for RLlib. In case you would like to support more such env packages, add the necessary imports and construction logic below. Args: env_context: The env context object to configure the env. Note that this is a config dict, plus the properties: `worker_index`, `vector_index`, and `remote`. env_descriptor: The env descriptor as a gym-registered string, e.g. "CartPole-v1", "ale_py:ALE/Breakout-v5". Alternatively, the gym.Env subclass to use. Returns: The actual gym environment object.
