Koichi ITO 819871cc4e Enable Style/MapToHash cop 
Ruby 2.6 added block argument processing to `Enumerable#to_h`.
https://bugs.ruby-lang.org/issues/15143

Rails 7 requires Ruby 2.7.0 or higher, so the new feature can use it.
`Style/MapToHash` cop will detect it. And this cop in the `Style` department,
but this seems to improve performance as follows:

```ruby
# map_to_hash.rb
require 'benchmark/ips'

ARRAY = (1..100).to_a
HASH = {foo: 1, bar: 2}

Benchmark.ips do |x|
  x.report('array.map.to_h') { ARRAY.map { |v| [v, v * 2] }.to_h }
  x.report('array.to_h')     { ARRAY.to_h { |v| [v, v * 2] } }

  x.compare!
end

Benchmark.ips do |x|
  x.report('hash.map.to_h') { HASH.map { |k, v| [k.to_s, v * 2] }.to_h }
  x.report('hash.to_h')     { HASH.to_h { |k, v| [k.to_s, v * 2] } }

  x.compare!
end
```

```console
% ruby map_to_hash.rb

Action Text

Action Text brings rich text content and editing to Rails. It includes the Trix editor that handles everything from formatting to links to quotes to lists to embedded images and galleries. The rich text content generated by the Trix editor is saved in its own RichText model that's associated with any existing Active Record model in the application. Any embedded images (or other attachments) are automatically stored using Active Storage and associated with the included RichText model.

You can read more about Action Text in the Action Text Overview guide.

Development

The JavaScript for Action Text is distributed both as a npm module under @rails/actiontext and via the asset pipeline as actiontext.js (and we mirror Trix as trix.js). To ensure that the latter remains in sync, you must run yarn build and checkin the artifacts whenever the JavaScript source or the Trix dependency is bumped. CSS changes must be brought over manually to app/assets/stylesheets/trix.css
