Add foreign key to active_storage_attachments for `blob_id` via new migration
We need this in order to be able to add this migration for users that
use ActiveStorage during update their apps from Rails 5.2 to Rails 6.0.
Related to #33405
`rake app:update` should update active_storage
`rake app:update` should execute `rake active_storage:update`
if it is used in the app that is being updated.
It will add new active_storage's migrations to users' apps during update Rails.
