The org-roam note exporter and its tests/fixtures now live in the doom
configuration (~/.doom.d/qwan) as org-roam-export-blog.el: renamed to
the org-roam- prefix so M-x org-roam-export-blog is discoverable, with
a configurable repo root and a new jekyll draft target.
Drop the test-elisp make target: it pointed at the moved files.
