Reformat Terce/Sext/None capitulum text as multi-line block scalars

Every capitulum-*.yml under the three Little Hours combined the chapter,
"R. Deo grátias"/"Thanks be to God", and the trailing V./R. pair into one
flat single-line string. The .lang-column CSS already renders on
white-space: pre-line (as little-hour-conclusio.yml's block-scalar text
already demonstrated), so the run-together rendering was purely a missing
line-break bug in the source YAML, not a CSS or resolver issue.
