Restore the `lookup_store` compatibility to accept config as a single object

9845cd63 broke configuring a cache store like so:

    config.cache_store = :redis_cache_store, config_for("redis/cache")

Rails::Application#config_for returns an ActiveSupport::OrderedOptions. By default, the Array#extract_options! core extension won't extract instances of Hash subclasses. Add ActiveSupport::OrderedOptions#extractable_options? and have it return true to fix.

Fix ActiveStorage::Blob → ActionText::TrixAttachment conversion

Action Cable's JavaScript library can optionally be imported as an ES6 module via `import { … } from "@rails/actioncable/src"`, but that module is broken in most of the releases published on npm:

```
ERROR in ./node_modules/@rails/actioncable/src/connection.js
Module not found: Error: Can't resolve './internal' in './node_modules/@rails/actioncable/src'
 @ ./node_modules/@rails/actioncable/src/connection.js
 @ ./node_modules/@rails/actioncable/src/index.js
```

Because `internal.js` was gitignored, it would only be included if the publisher happened to have it generated locally. Committing it to version control ensures that won't happen, and gives us better visibility into changes over time.

Update to listen 3.2

* Backport of https://github.com/rails/rails/pull/37788 to 6.0-stable
* https://github.com/guard/listen/releases/tag/v3.2.0
* https://github.com/guard/listen/issues/465
* `listen` removed the unmaintained `ruby_dep` dependency, which
  incorrectly shows warnings when running on TruffleRuby.

This reverts commit 84d58d2a.

This will generate a Rails 6.0 application running against Rails 6.1.
This doesn't means the app will have incompatibilities but it also
doesn't give the full 6.1 experience. We are revisiting the
implementation of this command for now.

* Allow system tests using Rack::Test to run without Chrome

If you require "action_dispatch/system_test_case", the driven_by method
will be executed immediately.

* https://github.com/rails/rails/blob/v6.0.0/actionpack/lib/action_dispatch/system_test_case.rb#L162

Then the preload method is called in SystemTesting::Driver#initialize.

* https://github.com/rails/rails/blob/v6.0.0/actionpack/lib/action_dispatch/system_testing/driver.rb#L13
* https://github.com/rails/rails/blob/v6.0.0/actionpack/lib/action_dispatch/system_testing/browser.rb#L46-L63

Therefore, a "Webdrivers::BrowserNotFound" error occurs in the browser
preloading when you run system tests witout Chrome.

This commit avoid the error by lazy configuring the driver.

ref: #37410

* Don't preload the browser with :rack_test

If users specify `driven_by(:rack_test)`, it uses Chrome by default arguments.
However, `Rack::Test` does not use a browser and does not need to be preloaded.

Furthermore, it occurs `Webdrivers::BrowserNotFound` when run in
a container (or a machine) without Chrome.

If they are not included in this "test types" list, they're counted
towards app code lines, not test lines.
