Fix typos [ci skip]

I wrote this shell script to find words from the Rails repo,
so I can paste them into https://www.horsepaste.com/ for
the [codenames game](https://en.m.wikipedia.org/wiki/Codenames_(board_game)).

```bash
git grep -Il '' | \
  grep -v -E "CHANGELOG|Gemfile|gemspec|package\.json|yarn\.lock" | \
  xargs cat | \
  sed '/[^ ]\{10,\}/d' | \
  sed 's/\([A-Z]\)/ \1/g' | \
  tr 'A-Z' 'a-z' | \
  tr -c -s 'a-z' '\n' | \
  sed '/^.\{0,3\}$/d' | \
  sort | \
  uniq | \
  tr '\n' ',' | \
  pbcopy
```

You can see the result in https://www.horsepaste.com/rails-fixed.
Click "Next game" to cycle the words.

Found some typos in the codebase from this 😂

This is how I generated the list of possible typos:

```bash
git grep -Il '' | \
  grep -v -E "CHANGELOG|Gemfile|gemspec|package\.json|yarn\.lock" | \
  xargs cat | \
  sed '/[^ ]\{10,\}/d' | \
  sed 's/\([A-Z]\)/ \1/g' | \
  tr 'A-Z' 'a-z' | \
  tr -c -s 'a-z' '\n' | \
  sed '/^.\{0,3\}$/d' | \
  sort | \
  uniq | \
  aspell --ignore-case list
```

I manually reviewed the list and made the corrections
in this commit. The rest on the list are either:

* Bugs in my script: it split things like "doesn't" into
  "doesn" and "t", if find things like `#ffffff` and
  extracts "ffffff" as a word, etc
* British spelling: honour, optimised
* Foreign words: bonjour, espanol
* Names: nginx, hanekawa
* Technical words: mutex, xhtml
* Portmanteau words: autosave, nodelist
* Invented words: camelize, coachee
* Shortened words: attrs, repo
* Deliberate typos: hllo, hillo (used in code examples, etc)
* Lorem ipsum words: arcu, euismod

This is the [output](https://gist.github.com/chancancode/eb0b573d667dc31906f33f1fb0b22313)
of the script *after* fixing the typos included in this
commit. In theory, someone can run that command again in
the future and compare the output to catch new typos (i.e.
using my list to filter out known typos).

Limitations: the aspell dictionary could be wrong, I
could have miss things, and my script ignores words that
are less than 3 characters or longer than 10 characters.
