Add historical reference to early work on meta prompting

[hatgit]

Summary

This PR adds a reference to an earlier community discussion "https://community.openai.com/t/meta-prompting-concept-asking-chat-gpt-for-the-best-prompt-for-your-desired-completion-then-to-revise-it-before-using-it/248619" about meta prompting, a concept I originally coined over a year ago and documented extensively in an ebook. Since OpenAI’s Cookbook now discusses meta prompting, I believe linking to this original post will provide valuable historical context and additional resources for users who want to explore the evolution of the technique.

Motivation

Metaprompting is becoming an essential strategy for prompt engineering, and acknowledging early contributions fosters a more comprehensive understanding of the topic. The linked post presents practical insights and discussions that complement the Cookbook’s guidance, helping users refine their approach.

I appreciate your consideration and am happy to make any adjustments needed to align with OpenAI’s documentation standards.
