Wrong validations on Parameters in TGI python library

Reproduction

Frequency penalty is validated to be strictly positive in the python library type validation, but is validated to be in the range [-2.0, 2.0] in the actual webserver. This means that i can send a REST API request to TGI with frequency penalty < 0 but will run into validation error when doing it via the text generation client

from text_generation import Client

endpoint_url = "https://YOUR_ENDPOINT.endpoints.huggingface.cloud"

client = Client(endpoint_url)
text = client.generate("Why is the sky blue?", frequency_penalty=-1.0).generated_text
print(text)
# ' Rayleigh scattering'

Expected behavior

No validation errors for frequency_penalty in the range [-2.0, 2.0]
