Wrong flash message is rendered when signing out

Environment

• Ruby 3.0.3p157
• Rails 7.0.4
• Devise 4.8.1

Current behavior

When a signed-in user visits destroy_user_session_path the flash message is "You need to sign in before continuing." (en.devise.failure.unauthenticated)

For reference, the link is <%= link_to 'Sign out', destroy_user_session_path, data: { turbo_method: :delete } %>

Expected behavior

When a signed-in user visits destroy_user_session_path the flash message should be "Signed out successfully."(en.devise.sessions.signed_out)

I fixed this by adding a sessions controller:

class SessionsController < Devise::SessionsController
  def destroy
    super do
      return redirect_to new_user_session_path, notice: I18n.t('devise.sessions.signed_out'), status: :see_other
    end
  end
end

The main branch should contain all that's necessary for fully working with Turbo now, which should fix this. A new version will be released soon, but feel free to test it out from the main branch in the meantime, and report back on any issues. Thanks.
