Langchain Chatbot 0.2

I decided to migrate the project into a Discord bot until the website is released. Both parts of the project will be maintained but the website will be my next main priority. Read readme.md for more details on how to utilize this update.

The Langchain Chatbot has many features of which are listed below:
✅ Credential Manager (OpenAI Keys)
✅ Space Manager (Ingestions)
✅ Documentation Ingester (For readthedocs.io sites)
ℹ️ Re-adding PDF Ingester (Will be implemented along with docx, doc, excel, etc.)
