Requiring _just_ the `Aws::SNS::MessageVerifier` does not work as it
references other classes in the AWS SDK that are not in this one class.
Bringing in the entire SNS SDK verifies the authenticity correctly.
The Frameworks collection was missing actiontext and actionmailbox,
this would mean they are skipped when running any tasks that
iterated through this collection
changes include
Breaking up frameworks declaration into multiple lines and put
them in order. This should make adding to the list easier and
if you need to scan it, they will be in order you would expect
Add `package` task to both actiontext and actionmailbox
- config.load_defaults 6.0 in the dummy app and
fix the test since by default rails 6.0 configured
does not generate "utf8" hidden input, see #32125
- Use `ActiveRecord::Migration[6.0]` in the dummy app
since actiontext will be since Rails 6.0
- Fix `CreateActiveStorageTables` migration in the dummy app.
Add `t.foreign_key :active_storage_blobs, column: :blob_id`
It was added in 2ae3a29508e.
- `rails/actiontext$ yarn install`
Since Action Mailbox will be introduced in Rails 6.0,
it makes more sense to generate migration of that version.
Also I changed its test dummy app to use default 6.0 configs.
