Replace org #+KEYWORDS with #+keywords

As of ~2 years ago, lower case keywords became the standard (though they
are handled case insensitive, as always):
https://code.orgmode.org/bzg/org-mode/commit/13424336a6f30c50952d291e7a82906c1210daf0

Upper case keywords are exclusive to the manual:

- https://orgmode.org/list/87tuuw3n15.fsf@nicolasgoaziou.fr/
