Drop the redundant (Exodus)/(Deuteronomy) parenthetical from canticle names

Both Canticle of Moses entries carried a book-name parenthetical in
their display name, redundant with (and now, since the last commit,
duplicated verbatim by) the citation shown right underneath. Only one
canticle is ever displayed per day, so there's nothing to disambiguate
in the UI -- trim to plain "Canticle of Moses" for both.

Verse numbering is the breviary's own liturgical division for chant, not always identical to standard Bible chapter:verse numbering.
