feature(rjy): add mamujoco env and related configs

[nighood]

1. MAmujoco Environment Integration: I have added support for the MAmujoco environment and successfully adapted it for use with LightZero. For detailed information about the MAmujoco environment, please refer to the original repository at MaMuJoCo Environments.

2. Independent Learning Pipeline: A new independent learning pipeline has been introduced to the project. This pipeline is currently integrated with the existing codebase and can be activated by setting the 'multi_agent' parameter accordingly.

These updates aim to enhance the project's functionality and scalability, providing a robust framework for multi-agent learning scenarios.
