### Reproduction

There is a small typographical error in the documentation for Greedy Search.

https://github.com/huggingface/transformers/blob/ff20f9cf3615a8638023bc82925573cb9d0f3560/docs/source/en/generation_strategies.mdx?plain=1#L149-L152


### Proposed Solution

This could be fixed by just rewriting this to:
```python
[`generate`] uses greedy search decoding by default so you don't have to pass any parameters to enable it. This means the parameters `num_beams` is set to 1 and `do_sample=False`.
```
Sure, would you like to suggest a PR?<|||||>Yeah, I can open a PR to fix this.
