[meta] Fix missing hyphens for prefixes - Words starting with "un"

Problem/Motivation

Quoted from parent issue:

Discovered at #2972224: Add .cspell.json to automate spellchecking in Drupal core, and pointed by @xjm in https://www.drupal.org/project/drupal/issues/3122088#comment-13628724

@xjm:

Should be hyphenated (un-assign, de-prioritize, re-render, etc.)

There's an interesting question of where to draw the line for these. Generally in English these prefixes are morphologically productive with a hyphen, and get de-hyphenated when the word is adopted into common usage. "Denormalize", "Unsanitized", "Uninstantiated" etc. are all obviously in common usage in programming. "Unsticky", "Unrevisionable", and the like are Drupal terminology, and I'm surprised that "unpublish" and friends aren't already in the main dictionary.

The parent issue tried to fix all words that should be hyphenated, but the patch for this was getting too big thus making it tricky to review. Also there were some debate about which words should be hyphenated, and which shouldn't. So they argued it would be better to separate the issue into 3 smaller ones (one each for words starting with 're', 'de' and 'un'). (see comment links bellow)

#3138768 #26.2 @xjm talks about the presave word and suggests to divide the issue.
#3138768 #31 @longwave agrees to divide the issue and says it's getting tricky to review.
#3138768 #36 @davidhernandez questions about if some words should be hyphenated.
#3138768 #38 @quietone agrees with @longwave about creating separated issues.

Proposed resolution

Check and decide as a group, with first-language speakers contributing, which of the following words are correct in Drupal and which should be hyphenated, then fix them as needed on the code.

1. unban -> TODO: Look up context
2. uncacheable -> un-cacheable
3. uncategorized -> un-categorized (? – check if this is in the dictionary)
4. ungroup -> un-group
5. ungroupable -> un-groupable
6. unindexed -> un-indexed
7. unmanaged -> TODO: Look up context
8. unminified -> un-minified (? – maybe de-minified)
9. unmoderated -> un-moderated
10. unpromote -> un-promote
11. unpublish -> un-publish (? – check dictionary on this)
12. unpublishing -> un-publishing (? - check dictionary on this)
13. unrevisionable -> un-revisionable
14. unrouted -> TODO: Look up context
15. unserialized -> un-serialized
16. unsets -> un-sets (? – check dictionary on this)
17. unsetting -> un-setting (? – check dictionary on this)
18. unsticky -> un-sticky
19. untabbable -> TODO: Look up context

Remaining tasks

1. First, probably reduce the list above (as a non-native English speaker I couldn't remove all the 'obviously unhyphenated' words before posting here).
2. Decide as a group what to do with each word.
3. Remove and fix the words as defined by the group.
4. Review.
5. Commit.
