Issue:
`max_tokens`'s default in docstring of `InferenceClient::chat_completion`'s  is 20 but that of TGI is 100
Hi there!🤗

`InferenceClient::chat_completion`'s docstring states that `max_tokens`'s default value is `20` but it seems that of the TGI is `100`.

https://github.com/huggingface/huggingface_hub/blob/8a99deb4e1c2c70ed180d4429e9da48902cd39bf/src/huggingface_hub/inference/_client.py#L586-L587

https://github.com/huggingface/text-generation-inference/blob/6e3220529df5906ae586031873b7865e9923040b/router/src/lib.rs#L939

Pull request:
[InferenceClient] Update `max_tokens` and `max_new_tokens` default value in docstring
fixes #2652.

tiny PR to fix incorrect default value of `max_tokens` and `max_new_tokens` in `InferenceClient.text_generation()` and `InferenceClient.chat_completion()` docstrings, reflecting the default values in [text-generation-inference/lib.rs](https://github.com/huggingface/text-generation-inference/blob/main/router/src/lib.rs). 
The default value in `InferenceClient.chat_completion()` was incorrectly documented as 20 instead of 100. The `max_new_tokens` parameter default value was also added in `InferenceClient.text_generation()` docstring, given that it's an important generation parameter.

 In addition to the [`HfApi`], the `huggingface_hub` library provides [`HfFileSystem`], a pythonic [fsspec-compatible](https://filesystem-spec.readthedocs.io/en/latest/) file interface to the Hugging Face Hub. The [`HfFileSystem`] builds on top of the [`HfApi`] and offers typical filesystem style operations like `cp`, `mv`, `ls`, `du`, `glob`, `get_file`, and `put_file`.
 
+<Tip warning={true}>
+
+  [`HfFileSystem`] provides fsspec compatibility, which is useful for libraries that require it (e.g., reading
+  Hugging Face datasets directly with `pandas`). However, it introduces additional overhead due to this compatibility
+  layer. For better performance and reliability, it's recommended to use [`HfApi`] methods when possible.
