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.

Tradétur enim Géntibus, et illudétur, et flagellábitur, et conspuétur: et postquam flagelláverint, occídent eum, et tértia die resúrget. Et ipsi nihil horum intellexérunt, et erat verbum istud abscónditum ab eis, et non intellegébant quæ dicebántur. Factum est autem, cum appropinquáret Jéricho, cæcus quidam sedébat secus viam, mendícans. Et cum audíret turbam prætereúntem, interrogábat, quid hoc esset. Dixérunt autem ei, quod Jesus Nazarénus transíret. Et clamávit, dicens: Jesu, fili David, miserére mei. Et qui præíbant, increpábant eum, ut tacéret. Ipse vero multo magis clamábat: Fili David, miserére mei. Stans autem Jesus, jussit illum addúci ad se. Et cum appropinquásset, interrogávit illum, dicens: Quid tibi vis fáciam? At ille dixit: Dómine, ut vídeam. Et Jesus dixit illi: Réspice, fides tua te salvum fecit. Et conféstim vidit, et sequebátur illum, magníficans Deum. Et omnis plebs ut vidit, dedit laudem Deo.

+        At that time, Jesus taking to Himself the Twelve said to them, Behold, we are going up to Jerusalem, and all things that have been written by the prophets concerning the Son of Man will be accomplished. For He will be delivered to the Gentiles, and will be mocked and scourged and spit upon; and after they have scourged Him, they will put Him to death; and on the third day He will rise again. And they understood none of these things and this saying was hidden from them, neither did they get to know the things that were being said. Now it came to pass as He drew near to Jericho, that a certain blind man was sitting by the wayside, begging; but hearing a crowd passing by, he inquired what this might be. And they told him that Jesus of Nazareth was passing by. And he cried out, saying, Jesus, Son of David, have mercy on me! And they who went in front angrily tried to silence him. But he cried out all the louder, Son of David, have mercy on me! Then Jesus stopped and commanded that he should be brought to Him. And when he drew near, He asked him, saying, What would you have Me do for you? And he said, Lord, that I may see. And Jesus said to him, Receive your sight, your faith has saved you. And at once he received his sight, and followed Him, glorifying God. And all the people upon seeing it gave praise to God.
