CLDR-18056 skintone with facing right

[macchiati]

CLDR-18056

Adds skintones to the right-facing emoji. These are emoji that add joiner+right_facing_arrow to point to the right. It also fixes 2 other problems: the "facing right" was not added to annotations, and in the name it didn't have a colon before it like other modifiers.

Example 1, with skin tones

<annotation cp="🚶🏻‍➡">drentel | gang | lang treë gee | loop | looppas | looptempo | lopende man | lopende persoon | slenter | stap | swerf | tempo | voetganger | wandel</annotation>
<annotation cp="🚶🏻‍➡" type="tts">voetganger kyk na regs</annotation>

becomes

<annotation cp="🚶🏻‍➡">drentel | gang | kyk | lang treë gee | ligte velkleur | loop | looppas | looptempo | lopende man | lopende persoon | na | regs | slenter | stap | swerf | tempo | voetganger | wandel</annotation>
<annotation cp="🚶🏻‍➡" type="tts">voetganger**: ligte velkleur,** kyk na regs</annotation>

Example 2, without skin tones

<annotation cp="🚶‍➡">drentel | gang | lang treë gee | loop | looppas | looptempo | lopende man | lopende persoon | slenter | stap | swerf | tempo | voetganger | wandel</annotation>
<annotation cp="🚶‍➡" type="tts">voetganger kyk na regs</annotation>

becomes

<annotation cp="🚶‍➡">drentel | gang | kyk | lang treë gee | loop | looppas | looptempo | lopende man | lopende persoon | na | regs | slenter | stap | swerf | tempo | voetganger | wandel</annotation>
<annotation cp="🚶‍➡" type="tts">voetganger**:** kyk na regs</annotation>

Reviewer:

• There are many changes in the data files, so just spot check a couple of cases in a couple of languages you know.
• For code changes:

tools/cldr-code/src/main/java/org/unicode/cldr/util/Annotations.java

• Made the synthesize method public for testing
• The code around if (code.contains(EmojiConstants.JOINER_STRING)) { got simpler, because we now just remove the arrow from code, and add it to rem. That allows it to fall through properly to private Annotations getBasePlusRemainder(, which handles the code.
  • Detecting if (mod == BLACK_RIGHTWARDS_ARROW.codePointAt(0)) { and just setting a flag
  • At the end, if that flag is set, then it adds the words from the rightwardsArrowPattern.

tools/cldr-code/src/test/java/org/unicode/cldr/unittest/TestAnnotations.java

• Restored TestUniqueness. That tests for exactly this kind of failure, and shouldn't have been removed unless a replacement was ready.

• Added testCompleteness, that all emoji have English annotations.

• Added testRightFacing, which has specific test cases for this problem.

• This PR completes the ticket.
