Describe the bug

I follow and run the same code in the documentation: https://mmengine.readthedocs.io/zh_CN/latest/tutorials/config.html#id12
but it reports FileNotFoundError.

Reproduction

1. python example.py

from mmengine.hub import get_model
model = get_model(
    'mmdet::faster_rcnn/faster_rcnn_r50_fpn_1x_coco.py', pretrained=True)
print(type(model))

2. Did you make any modifications on the code or config? Did you understand what you have modified?
   Not

3. What dataset did you use?
   Not applied.

Environment

1. Please run python mmdet/utils/collect_env.py to collect necessary environment information and paste it here.
2. You may add addition that may be helpful for locating the problem, such as
   • How you installed PyTorch [e.g., pip, conda, source]
   • Other environment variables that may be related (such as $PATH, $LD_LIBRARY_PATH, $PYTHONPATH, etc.)

openmim 0.3.2

Thank @zhouzaida for providing a lot of help!
We found that it is caused by a wrong filename that appeared in the documentation.
mmdet::faster_rcnn/faster_rcnn_r50_fpn_1x_coco.py -> mmdet::faster_rcnn/faster-rcnn_r50_fpn_1x_coco.py
I have fixed in #659
