Remove spurious mid-nocturn versicle from ferial Matins

The 1-nocturn ferial branch was rendering a V./R. versicle stuck
mid-list, as if marking a nocturn boundary that doesn't exist in a
single continuous nocturn. Live-verified against the reference engine
(Pofficium.pl, Monastic Tridentinum 1617) for Wednesday and Thursday:
the real office runs straight from the last psalm to the Capitulum,
with no versicle anywhere in the psalmody. The embedded mid-list V./R.
line in the source Psalmi matutinum.txt is inert there and was never
actually emitted by the engine — matins-ferial-antiphons.yml's
versicle field was a documented-but-unverified assumption, not real
content.
