From now on Doom will enforce two conventions for its org files for
consistency's sake:
- Lower-case meta-lines in org files, like #+begin_src, #+name, or
#+end_quote (only exception are the top-level ones, like #+TITLE and
#+STARTUP).
- Use 'emacs-lisp' as the lang specifier for elisp blocks rather than
'elisp'. Emacs doesn't natively recognize the latter.
This will be reflected in our rewritten docs/*.org and module
README.org's.
