MLM Pretraining missing bbox inputs

[darraghdog]

Hi, Great work on the package. It seems on some of the model classes, eg. BrosLMHeadModel, the code misses the bbox inputs. Example below. Correct me if I misunderstood, but I guess bbox should be added here. If you would like I can put in a PR to fix it here and in the other places like BrosForSequenceClassification and BrosPreTrainedModel.

Hi, thank you for your interest in our work! You are right. Sorry for the confusion. (When implementing the code, I copied and pasted the modeling_bert.py of Hugging Face's transformers and modified only a part...) I'd appreciate if you could open the PR!
