Fix duplicate line number 40.566 in nonnusdionysiaca.xml.

Comparing to a book scan,
https://archive.org/details/dionysiaca03nonnuoft/page/192/mode/1up
the second instance of line number 566 should have been 567 instead.

Perhaps complicated by line 567 being typographically split in the
printed version. Though unlike 37.625, here the markup does not indicate
the typographical break.
