Fix ASR pipeline bug when using some kwargs

[jhj0517]

What does this PR do?

Always Thanks for your work.
In AutomaticSpeechRecognitionPipeline, when using temperature, no_speech_threshold and logprob_threshold kwargs, token_ids has List of float types and it occurs following TypeError:

  File "C:\Whisper_Project\Whisper-WebUI\venv\Lib\site-packages\transformers\tokenization_utils_fast.py", line 657, in _decode
    text = self._tokenizer.decode(token_ids, skip_special_tokens=skip_special_tokens)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: argument 'ids': 'float' object cannot be interpreted as an integer

Reproduction

from transformers import pipeline

input_path = "test_audio.mp3"

pipe = pipeline(
    "automatic-speech-recognition",
    model="openai/whisper-tiny",
    torch_dtype="float16",
    device="cuda",
)

kwargs = {
    "language": "en",
    "task": "transcribe",
    "temperature": 0.7,
    "no_speech_threshold": 0.6,
    "logprob_threshold": -1.0,
}
segments = pipe(
    inputs=[input_path],
    return_timestamps=True,
    chunk_length_s=30,
    batch_size=24,
    generate_kwargs=kwargs
)

This PR fixes the error by casting it to list of int if its type is float.

This may be caused by to_py_obj():

transformers/src/transformers/tokenization_utils_base.py

Line 3818 in a06a0d1

token_ids = to_py_obj(token_ids)

transformers/src/transformers/utils/generic.py

It's converted to list of float by this function when it should be list of int. This only occurs when using temperature, no_speech_threshold, and logprob_threshold parameters in the pipeline.
