Fix: Tool call names

[csansoon]

Vercel does not eat the tools configuration right away, and instead requires an additional transformation. Within this transformation, we were not maintaining the tool name

Now, the name is maintained:

this is because you've represented the tool calls as an array of tools, if you pass an object it works perfectly, i wouldn't apply custom transformations if not needed, just document the right way of declaring tools:

provider: Real openai
model: gpt-4o-mini
tools:
  weather:
    description: Gets the weather for particular location
    parameters:
      type: object
      properties:
        location:
          type: string
          description: Location to get the weather for
      required:
        - location
      additionalProperties: false

@geclos Hmm but that differs from the OpenAI's API documentation. I guess we could just document our way to do it though
