[PATCH] Fix date in org-latex--format-spec

Hi all,

This is my first time posting here. Sorry in advance if I did something
wrong.
I tried customizing org-latex-title-command with a "%D" placeholder but the
LaTeX was not compiling since this placeholder was being replaced by the
string

((latex-fragment (:value \today :begin 1 :end 7 :post-blank 0 :parent #0)))

I could not find this in previous issues and the code in the main branch
still reproduced this error. The problem seems to be a missing call to
org-export-data in the function org-latex--format-spec. Perhaps it is not
necessary but I'm attaching the one-line patch that fixed things for me.
