### Information

- [X] The official example scripts
- [ ] My own modified scripts

### Tasks

- [X] An officially supported task in the `examples` folder (such as GLUE/SQuAD, ...)
- [ ] My own task or dataset (give details below)

### Reproduction

In transformers v4.26.1, the following script will output right language, some chinese text. It's the right task "transcribe".
However, in version 4.27.2, it will output translated english text, which is another task "translate".

### Expected behavior

Do ASR, and Output chinese
cc @ArthurZucker and @sanchit-gandhi 🙏 <|||||>Hey! As you can see [here](https://github.com/ArthurZucker/transformers/blob/d2854e753bcfd62dce2f968d6088232d0fc41f8c/src/transformers/models/whisper/modeling_whisper.py#L1586) the default (if the generation_config does not have a `task` set is still `transcribe`. What changed is the `configuration.json` see this [commit](https://huggingface.co/openai/whisper-large-v2/commit/e823955b7861a1d66fef509b8601ada6d7762c03) where the default went from `transcribe` ( 50358) to `translate` (50359 in the forced_decoder_ids). The update in transformers just makes sure to properly use this, while the previous version did not take it into account. <|||||>This is more a fix than a breaking change IMO<|||||>Thank you for your explanation.
