Better Docs with ChatGPT support

A newly revamped documentation website has been launched, featuring ChatGPT support and an interactive learning experience. This update includes rewritten content, new tutorials, quickstart guides, and a section dedicated to Graphite and an AI toolkit. The integration of ChatGPT aims to provide instant responses and personalized assistance, enhancing the user experience by making browsing and searching through documentation more engaging and efficient. Additionally, an API Playground is introduced, allowing users to test Auth and Storage endpoints on a local Nhost instance. This initiative underscores the importance of documentation in technical products, with plans for ongoing improvements and content expansion.
