Add full Gospel pericopes to post-Epiphany through Palm Sunday Matins readings

Same gap as the Advent/Christmas sweep: Nocturn 3's patristic homily
appeared with no Gospel pericope before it. Authors the full text for
post-epiphany-1 through -6, septuagesima/sexagesima/quinquagesima,
lent-1 through -4, passion-sunday, and palm-sunday.

Palm Sunday needed a different source than the rest: its Missale
[Evangelium] tag is the Passion narrative (Matt 26-27) proclaimed at
Mass, not the entry-into-Jerusalem pericope (Matt 21:1-9) its own
Nocturn 3 homily is actually about — that shorter Gospel is instead
read at the Blessing of Palms, sourced from there.

Et deficiénte vino, dicit Mater Jesu ad eum: Vinum non habent. Et dicit ei Jesus: Quid mihi et tibi est, mulier? nondum venit hora mea. Dicit Mater ejus minístris: Quodcúmque díxerit vobis, fácite. Erant autem ibi lapídeæ hýdriæ sex pósitæ secúndum purificatiónem Judæórum, capiéntes síngulæ metrétas binas vel ternas. Dicit eis Jesus: Implete hýdrias aqua. Et implevérunt eas usque ad summum. Et dicit eis Jesus: Hauríte nunc, et ferte architriclíno. Et tulérunt. Ut autem gustávit architriclínus aquam vinum fáctam, et non sciébat unde esset, minístri autem sciébant, qui háuserant aquam: vocat sponsum architriclínus, et dicit ei: Omnis homo primum bonum vinum ponit: et cum inebriáti fúerint, tunc id, quod detérius est. Tu autem servásti bonum vinum usque adhuc. Hoc fecit inítium signórum Jesus in Cana Galilǽæ: et manifestávit glóriam suam, et credidérunt in eum discípuli ejus.

+        At that time, a marriage took place at Cana of Galilee, and the mother of Jesus was there. Now Jesus too was invited to the marriage, and also His disciples. And the wine having run short, the mother of Jesus said to Him, They have no wine. And Jesus said to her, What would you have me do, woman? My hour has not yet come. His mother said to the attendants, Do whatever He tells you. Now six stone water-jars were placed there, after the Jewish manner of purification, each holding two or three measures. Jesus said to them, Fill the jars with water. And they filled them to the brim. And Jesus said to them, Draw out now, and take to the chief steward. And they took it to him. Now when the chief steward had tasted the water after it had become wine, not knowing whence it was - though the attendants who had drawn the water knew, - the chief steward called the bridegroom, and said to him, Every man at first sets forth the good wine, and when they have drunk freely, then that which is poorer. But you have kept the good wine until now. This first of His signs Jesus worked at Cana of Galilee; and He manifested His glory, and His disciples believed in Him.
