MO-Gymnasium 1.2.0 Release: Update Gymnasium to v1.0.0, New Mountaincar Environments, Documentation and Test Improvements, and more

Breaking Changes

• Similar to Gymnasium v1.0, VecEnvs now differ from normal Envs. The associated wrappers also differ. See Gymnasium 1.0.0 release notes.
• Wrappers have been moved to their wrappers subpackage, e.g., from mo_gymnasium import MORecordEpisodeStatistics -> from mo_gymnasium.wrappers import MORecordEpisodeStatistics. Vector wrappers can be found under mo-gymnasium.wrappers.vector. See the tests/ folder or our documentation for example usage.
