Removes wandb logging in AutoMate env (#2912)

# Description

wandb logging function is provided in rl_games script. So we remove the
wandb logging in task level. Also, we edit the task registration style
to help startup perf.

## Type of change

- Bug fix (non-breaking change which fixes an issue)
- This change requires a documentation update

## Checklist

- [ x ] I have run the [`pre-commit` checks](https://pre-commit.com/)
with `./isaaclab.sh --format`
- [ x ] I have made corresponding changes to the documentation
- [ x ] My changes generate no new warnings
- [ ] I have added tests that prove my fix is effective or that my
feature works
- [ ] I have updated the changelog and the corresponding version in the
extension's `config/extension.toml` file
- [ x ] I have added my name to the `CONTRIBUTORS.md` or my name already
exists there

 * |disassembly-link|: The plug starts inserted in the socket. A low-level controller lifts the plug out and moves it to a random position. This process is purely scripted and does not involve any learned policy. Therefore, it does not require policy training or evaluation. The resulting trajectories serve as demonstrations for the reverse process, i.e., learning to assemble. To run disassembly for a specific task: ``python source/isaaclab_tasks/isaaclab_tasks/direct/automate/run_disassembly_w_id.py --assembly_id=ASSEMBLY_ID --disassembly_dir=DISASSEMBLY_DIR``. All generated trajectories are saved to a local directory ``DISASSEMBLY_DIR``.
 * |assembly-link|: The goal is to insert the plug into the socket. You can use this environment to train a policy via reinforcement learning or evaluate a pre-trained checkpoint.
 
-  * To train an assembly policy, we run the command ``python source/isaaclab_tasks/isaaclab_tasks/direct/automate/run_w_id.py --assembly_id=ASSEMBLY_ID --train``. We can customize the training process using the optional flags: ``--headless`` to run without opening the GUI windows, ``--max_iterations=MAX_ITERATIONS`` to set the number of training iterations, ``--num_envs=NUM_ENVS`` to set the number of parallel environments during training, ``--seed=SEED`` to assign the random seed, ``--wandb`` to enable logging to WandB (requires a WandB account). The policy checkpoints will be saved automatically during training in the directory ``logs/rl_games/Assembly/test``.
