Model arguments for get_convnext_model.

Hi there.

May you provide the arguments for "get_convnext_model" function to produce similar models to the lists here:
https://github.com/facebookresearch/ConvNeXt#results-and-pre-trained-models

In particular, I need them to generate "convnext_base_1k_224" and "convnext_xlarge_21k_1k_224".
