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-gmw-gmw)

>>> inputs = tokenizer(Hey how are you?, return_tensors=pt, padding=True)

>>> model = MarianMTModel.from_pretrained(Helsinki-NLP/opus-mt-tc-big-gmw-gmw)

>>> print(tokenizer.batch_decode(model.generate(**inputs)))
