/**
* Convert a formatted LangChain prompt (e.g. pulled from the hub) into
* a format expected by Anthropic's JS SDK.
*
* Requires the "@langchain/anthropic" package to be installed in addition
* to the Anthropic SDK.
*
* @example
* ```ts
* import { convertPromptToAnthropic } from "langsmith/utils/hub/anthropic";
* import { pull } from "langchain/hub";
*
* import Anthropic from '@anthropic-ai/sdk';
*
* const prompt = await pull("jacob/joke-generator");
* const formattedPrompt = await prompt.invoke({
* topic: "cats",
* });
*
* const { system, messages } = convertPromptToAnthropic(formattedPrompt);
*
* const anthropicClient = new Anthropic({
* apiKey: 'your_api_key',
* });
*
* const anthropicResponse = await anthropicClient.messages.create({
* model: "claude-3-5-sonnet-20240620",
* max_tokens: 1024,
* stream: false,
* system,
* messages,
* });
* ```
* @param formattedPrompt
