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 AutoTokenizer, MarianMTModel
>>> tokenizer = AutoTokenizer.from_pretrained('Helsinki-NLP/opus-mt-tc-big-en-ces_slk')
>>> inputs = tokenizer("Hey! Let's learn together", return_tensors="pt", padding=True)
>>> model = MarianMTModel.from_pretrained('Helsinki-NLP/opus-mt-tc-big-en-ces_slk')
>>> print(tokenizer.batch_decode(model.generate(**inputs)))
['<pad> Pojďme se učit společně!</s>']
```
