Reproduction Steps

client = Mistral(
  async_client=httpx.AsyncClient(headers={"Custom-Header": "Value"}),
  server_url=base_url,
)

client.chat.complete_async(...) 

Expected Behavior

Header Custom-Header should be passed when making the call to the API

Additional Context

No response

Suggested Solutions

Issue is probably link to this line that call build_request without giving context wether or not it's an async call.
In the implementation of build_request the request is always created using client = self.sdk_configuration.client even if we are making an async request.
