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/871s50zn6p.fsf@nicolasgoaziou.fr/
- https://orgmode.org/list/87tuuw3n15.fsf@nicolasgoaziou.fr/

                            This belongs to the outer list element, and is aligned accordingly, since the NAME attribute is not indented deeply enough. It is not enough for the BEGIN alone to be aligned deeply if the block is meant to have a NAME.

                  Still in the shallower list element since the preceding example
                  block forced the deeper list element to terminate.
 Outside all lists.
