This pull request includes updates to the `docs/docs/integrations/chat/perplexity.ipynb` file to enhance the documentation for `ChatPerplexity`. The changes focus on demonstrating the use of Perplexity-specific parameters and supporting structured outputs for Tier 3+ users. Enhancements to documentation: * Added a new markdown cell explaining the use of Perplexity-specific parameters through the `ChatPerplexity` class, including parameters like `search_domain_filter`, `return_images`, `return_related_questions`, and `search_recency_filter` using the `extra_body` parameter. * Added a new code cell demonstrating how to invoke `ChatPerplexity` with the `extra_body` parameter to filter search recency. Support for structured outputs: * Added a new markdown cell explaining that `ChatPerplexity` supports structured outputs for Tier 3+ users. * Added a new code cell demonstrating how to use `ChatPerplexity` with structured outputs by defining a `BaseModel` class and invoking the chat with structured output.[Copilot is generating a summary...]Thank you for contributing to LangChain! --------- Co-authored-by: Chester Curme <chester.curme@gmail.com>
