Tapioca v0.17.2 fails to generate signature for `AbstractController::Collector#turbo_stream`

After upgrading Tapioca to 0.17.2 (or more recent) and regenerating the RBI for actionpack, the signature for AbstractController::Collector#turbo_stream is missing.

The AbstractController::Collector methods are dynamically generated based on Mime::SET: https://github.com/rails/rails/blob/v8.0.2/actionpack/lib/abstract_controller/collector.rb#L18-L20

The turbo-rails gem registers the turbo_stream format in a Rails initializer: https://github.com/hotwired/turbo-rails/blob/v2.0.16/lib/turbo/engine.rb#L102-L104

So it looks like something changed in 0.17.2 that causes the Rails initializer to no longer be executed.

This is problematic for us because we have code in controllers like this:

respond_to do |format|
  format.turbo_stream do
    render(turbo_stream: ...)
  end
end

and after regenerating the RBI for actionpack, the code above produces a Sorbet error:

Method `turbo_stream` does not exist on `ActionController::MimeResponds::Collector`

Reproduce the missing signature by regenerating actionpack's RBI, then inspect actionpack/lib/abstract_controller/collector.rb and turbo-rails/lib/turbo/engine.rb to trace how turbo_stream is registered. Compare initializer execution around Tapioca 0.17.2 and verify that the generated RBI contains AbstractController::Collector#turbo_stream and the example controller no longer raises the Sorbet error.
