Update bros checkpoint

[jinhopark8345]

What does this PR do?

Update Bros checkpoint.

The naver-clova-ocr/bros-base-uncased checkpoint has bbox_projection layer in BrosEmbeddings class but this layer is moved to BrosBboxEmbeddings class. And users are expected to use jinho8345/bros-base-uncased checkpoint instead of naver-clova-ocr/bros-base-uncased.

• naver-clova-ocr/bros-base-uncased : original pretrained checkpoint from naver-clova-ocr
• jinho8345/bros-base-uncased : weights renamed version from naver-clova-ocr/bros-base-uncased using conversion script

Is there a reason why we did not go with creating new repos with naver-clova-ocr/bros-base-uncased-hf instead of a custom repo?

No reason at all. I also considered that it would be more reliable to use checkpoint that huggingface controls.

I'll ask for the models to be moved if that is okay with you?

[ydshieh]

I am not sure if @jinhopark8345 can move repo to naver-clova-ocr. Even for us, we will need naver-clova-ocr to approve I think.

Sorry merged this PR without waiting core maintainers' approval.

[jinhopark8345]

@ArthurZucker I can not move the repo to naver-clova-ocr as @ydshieh assumed. And I am sorry that I didn't mention about my concern earlier, @ydshieh.

[ArthurZucker]

I'll ask for the checkpoints to be move then 😉
