The checkpoint you are trying to load has model type `modernbert` but Transformers does not recognize this architecture

Hi,

I run the example code:

`from transformers import AutoTokenizer, AutoModelForMaskedLM

model_id = "answerdotai/ModernBERT-base"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForMaskedLM.from_pretrained(model_id)`

It shows an error:

`ValueError: The checkpoint you are trying to load has model type `modernbert` but Transformers does not recognize this architecture. This could be because of an issue with the checkpoint, or because your version of Transformers is out of date.
`

I have installed the up-to-date version:
Transformers=4.47.1
Flash-attn=2.7.2.post1

Could you please advise how to fix it? Thanks.
