Add full Gospel pericopes to post-Pentecost Sunday Matins readings

Closes the gap this whole sweep started from: Nocturn 3 on
post-pentecost-13/14 showed St. Augustine's homily with no Gospel
citation or text above it. Fixes all remaining post-pentecost-NN ids
(01-14, 16-24; -15 already had this from the original mechanism proof)
the same way as the rest of the sweep, plus Trinity Sunday's second
Nocturn 3 pair — the "Commemoration of the First Sunday after
Pentecost," whose Gospel (Luke 6:36-42) has no live date to source from
since Trinity always occupies that slot, so it's sourced from the
reference engine's preserved pre-displacement Mass propers file
instead. Also fixes a stray-space formatting glitch in
post-pentecost-19's existing homily text, found while sourcing.

Pharisǽus stans, hæc apud se orábat: Deus, grátias ago tibi, quia non sum sicut céteri hóminum: raptóres, injústi, adúlteri: velut étiam hic publicánus. Jejúno bis in sábbato: décimas do ómnium, quæ possídeo. Et publicánus a longe stans nolébat nec óculos ad cœlum leváre: sed percutiébat pectus suum, dicens: Deus, propítius esto mihi peccatóri. Dico vobis: descéndit hic justificátus in domum suam ab illo: quia omnis qui se exáltat, humiliábitur: et qui se humíliat, exaltábitur.

+        At that time, Jesus spoke this parable to some who trusted in themselves as being just and despised others. Two men went up to the temple to pray, the one a Pharisee and the other a publican. The Pharisee stood and began to pray thus within himself: ‘O God, I thank You that I am not like the rest of men, robbers, dishonest, adulterers, or even like this publican. I fast twice a week; I pay tithes of all that I possess.’ But the publican, standing afar off, would not so much as lift up his eyes to heaven, but kept striking his breast, saying, ‘O God, be merciful to me the sinner!’ I tell you, this man went back to his home justified rather than the other; for everyone who exalts himself shall be humbled, and he who humbles himself shall be exalted.
