lookahead with do_sample=True does not take temperature, top_k, top_p

Here `lookahead_generation` doesn't take `logits_warper` as input:

`logits_warper` is used in original `sample` to modify `next_tokens_scores`:

and to modifies logits by temperature, top_k, top_p...

```python
if generation_config.temperature is not None and generation_config.temperature != 1.0:
warpers.append(TemperatureLogitsWarper(generation_config.temperature))
if generation_config.top_k is not None and generation_config.top_k != 0:
warpers.append(TopKLogitsWarper(top_k=generation_config.top_k, min_tokens_to_keep=min_tokens_to_keep))
if generation_config.top_p is not None and generation_config.top_p < 1.0:
warpers.append(TopPLogitsWarper(top_p=generation_config.top_p, min_tokens_to_keep=min_tokens_to_keep))
```

This is not applied inside `lookahead_generation`. So with `do_sample=True` the temperature is always one
