propers: octave readings for Christmas's octave and Pentecost's

Christmas's stacking cluster (Dec 26-31): only day 6 (Dec 30) has its own
Matins reading -- the one day nothing else wins outright, confirmed via
its own Invitatory. St. Stephen, St. John, and the Holy Innocents' own
octaves (also active there, stacking) have no separate reading content
anywhere in this range -- every other day belongs entirely to whichever
saint natively wins it, same as Immaculate Conception's octave (no
Matins content at all beyond its own day, confirmed and left
unauthored -- checked, not skipped).

Pentecost's octave: days 2-7 all have real content, confirmed via a
consistent distinctive Invitatory throughout, including its own Ember
Saturday (day 7) -- Pentecost's own content governs Matins there despite
St. Felix I's stub-level commemoration that same day (see
tests/calendar/transfer.test.ts). Day 8 (Trinity Sunday) has none of its
own -- Trinity's own distinct office governs that day's actual Matins
content, so no reading is authored for it despite the octave mechanism
still commemorating Pentecost there. Two readings are direct Scripture
(Acts 19:1-9, Joel 2:23-28) with no source English rendered; used the
standard Douay-Rheims wording (verified, not draft) rather than the
project's own patristic-prose translations, matching how every other
Scripture citation in this project is sourced.

Also fixes two more instances of the recurring "dropped space after
capital I" source typo ("Icame" -> "I came").

+    Joël 2:25-26 25 Et reddam vobis annos, quos comédit locústa, bruchus, et rubígo, et erúca: fortitúdo mea magna quam misi in vos. 26 Et comedétis vescéntes, et saturabímini: et laudábitis nomen Dómini Dei vestri, qui fecit mirabília vobíscum: et non confundétur pópulus meus in sempitérnum.
+
+    Joël 2:27-28 27 Et sciétis quia in médio Israël ego sum, et ego Dóminus Deus vester, et non est ámplius: et non confundétur pópulus meus in ætérnum. 28 Et erit post hæc: effúndam spíritum meum super omnem carnem, et prophetábunt fílii vestri et fíliæ vestræ: senes vestri sómnia somniábunt, et júvenes vestri visiónes vidébunt.

+    23 And you, O children of Sion, rejoice, and be joyful in the Lord your God: because he hath given you a teacher of justice, and he will make the early and the latter rain to come down to you as in the beginning. 24 And the floors shall be full of wheat, and the presses shall overflow with wine and oil.
+
+    25 And I will restore to you the years which the locust, and the bruchus, and the mildew, and the palmerworm hath eaten; my great host which I sent upon you. 26 And you shall eat in plenty, and shall be filled: and you shall praise the name of the Lord your God, who hath done wonders with you: and my people shall not be confounded for ever.
+
+    27 And you shall know that I am in the midst of Israel: and I am the Lord your God, and there is none besides: and my people shall not be confounded for ever. 28 And it shall come to pass after this, that I will pour out my spirit upon all flesh: and your sons and your daughters shall prophesy: your old men shall dream dreams, and your young men shall see visions.
