Update test dummy application defaults

Affected gems:

* actionmailbox
* activestorage
* actiontext

This fixes the following warning:

DEPRECATION WARNING: Using legacy connection handling is deprecated. Please set
`legacy_connection_handling` to `false` in your application.

The new connection handling does not support `connection_handlers`
getter and setter.

Read more about how to migrate at: https://guides.rubyonrails.org/active_record_multiple_databases.html#migrate-to-the-new-connection-handling
 (called from require at ~/.gem/ruby/3.1.0/gems/zeitwerk-2.4.2/lib/zeitwerk/kernel.rb:34)
