Add llms.txt documentation support

[osterman]

what

• Added a new blog post detailing the implementation of the llms.txt standard.
• This standard aims to make Cloud Posse documentation more accessible to AI assistants.
• The new blog post explains the purpose of llms.txt, its benefits for users interacting with AI tools, and the technical implementation using docusaurus-plugin-llms.

why

• To improve the accuracy and relevance of AI-generated responses when users query about Cloud Posse tools and best practices.
• By providing curated content in machine-readable formats (/llms.txt and /llms-full.txt), AI assistants can reference up-to-date documentation directly, rather than relying on potentially stale training data.
• This aligns with the growing trend of AI integration in developer workflows and enhances developer velocity by providing faster, more precise information.
