WIP: Optiguides - vectorized knowledge base AI module

[raiseerco]

WIP

This PR will enable the AI chat with OP documentation taken from the Community hub.

• A Github Action will generate the .md files in https://github.com/raiseerco/ethernaut-app-kb/releases/tag/daily
• Those .md files will feed the vectorized kb used by OpenAI api
• The assistants API will use such vectorized kb to answer users' questions
• The default model was upgraded to gpt-4o-mini in order to expand token limit up to 200k (It'll allow users to query in all languages)
• Checks latest hash pushed to master in op-docs
