tools/pick-complete-translations.py: cherry-pick in chrono-order

repo.iter_commits() does reverse chronological order by default, which is
wrong for this, since it goes backwards through the git history.

 # cherry-pick complete translations from weblate
+#
+# This is too hard to get working right, so really, this should be
+# punted to the translators.  Weblate can automatically file a merge
+# request when a language hits 100% translated and 0% failed.
+#
+# This will probably fail to cherry-pick if a commit contains more
+# than one language.  In that case, reset everything, then manually
+# cherry-pick that one commit and push it.  Then run this again.
