Fix stale St. Damasus header comment on octave precedence

Claimed Semiduplex wins outright over the Advent feria with the feria
commemorated in return -- true when written, but no longer true after
the later octave-wins-class rework. Dec 11 falls inside the Immaculate
Conception octave, whose elevated wins:duplex threshold now outranks a
plain Semiduplex, so Damasus is actually demoted to a commemoration
and the Advent feria keeps the day. No behavior change, found and
confirmed live while authoring St. Juan Diego's neighboring entry.

+        In Mexico, on the hill of Tepeyac, in the year 1531, the God-bearing Virgin Mary,
+        as is piously handed down, appeared to the neophyte Juan Diego, and gave him a
+        command for Bishop Juan de Zumarraga, which she urgently repeated, that a church
+        was to be constructed in her name at that location. The bishop, however, requested
+        a sign. Then, while he was seeking the sacraments for his dying uncle far from the
+        place of the apparition, his loving Mother favored the neophyte with a third
+        vision, assured him of his uncle's health, and after he had gathered roses into his
+        cloak that had blossomed out of season, she ordered him to take them to the bishop.
+        The roses having spilled out in the sight of the bishop, an image of Mary,
+        impressed upon the cloak itself, according to the tradition, appeared to those
+        present in a wondrous manner. At first kept in the bishop's chapel, then
+        transferred to a shrine constructed on the hill of Tepeyac, it was finally moved to
+        a magnificent temple, to which Mexicans increasingly began to gather in droves, for
+        reasons of veneration and frequency of miracles. And therefore as an ever-present
+        defense, the Mexican bishops, to the applause of the whole people, chose the
+        Blessed Virgin Mary of Guadalupe as the first Patroness of the Mexican people,
+        which was duly confirmed by the apostolic authority of Benedict XIV. Leo XIII
+        adorned the sacred image with a golden crown on Columbus Day, 1895, by the agency
+        of the archbishop of Mexico. And St. Pius X declared the blessed Guadalupan Virgin
+        as the Patroness of all Latin America.
