support MambaYOLOWorld

[hezhengting]

What is the problem this feature will solve?

I was trying to run MambaYOLOWorld demo with the command:
python demo/image_demo.py --config configs/mamba2_yolo_world_s.py --checkpoint MambaYOLOWorld_s_pretrain_O365GoldG.pth --image myimage.jpg --text food

and I got error below. It seems mmyolo not support MambaYOLOWorldPAFPN?
KeyError: 'MambaYOLOWorldPAFPN is not in the mmyolo::model registry. Please check whether the value of MambaYOLOWorldPAFPN is correct or it was registered as expected. More details can be found at https://mmengine.readthedocs.io/en/latest/advanced_tutorials/config.html#import-the-custom-module'

What is the feature you are proposing to solve the problem?

Will mmyolo be updated to support MambaYOLOWorld?

What alternatives have you considered?
