Apparently, the convention (at least starting from 2018) is to make the
keywords and block names to be in lowercase as stated from one of the
following discussions at
https://orgmode.org/list/87tuuw3n15.fsf@nicolasgoaziou.fr/.
The files was updated with a one liner of shell. However, this is Emacs
and org-mode does have an API to let you do stuff in your config and
interact with the documents internally so it is not an elegant solution
in any way.
