Tasks: add function_to_apply's docstring for classification tasks (huggingface#1043)

This PR adds missing parameter description for `function_to_apply`. this
documentation is required since huggingface_hub's `InferenceClient`
documentation is automatically generated from the specs defined here
(See
[huggingface_hub/.github/workflows/update-inference-types.yaml](https://github.com/huggingface/huggingface_hub/blob/main/.github/workflows/update-inference-types.yaml)
for more details).

Note: the description was not technically missing since it's already
available in `ClassificationOutputTransform`'s description, but it
wasn't being properly inferred for the `function_to_apply` property.
