Update checkpoint for transformers>=4.29

Following the merge of [a PR](https://github.com/huggingface/transformers/pull/24310) in `transformers` it appeared that this model was not properly converted. This PR will fix the inference and was tested using the following script:
```python
>>> from transformers import MarianModel, MarianMTModel
>>> tokenizer = AutoTokenizer.from_pretrained(Helsinki-NLP/opus-mt-tc-big-en-ar)
>>> inputs = tokenizer(Hey! Let's learn together, return_tensors=pt, padding=True)
>>> model = MarianMTModel.from_pretrained(Helsinki-NLP/opus-mt-tc-big-en-ar)
>>> print(tokenizer.batch_decode(model.generate(**inputs)))
