Add gptel-org function

Implemented a gptel-org function to allow interacting with GPTel within an Org-Mode buffer, setting the appropriate system message for context. Updated init-org.el to load Emacs-Lisp and Python Babel languages and disabled org-confirm-babel-evaluate for smoother code execution.
