Installing Acquia DAM on Drupal Core 9.5.x throws error

Problem/Motivation

Installing the Acquia DAM module on Drupal Core 9.5.x throws following error:

In Route.php line 523:                                                                                       
  Routing requirement for "_acquia_dam_site_authenticated_access_check" must be a string.  

This is caused because of the change introduced in #3446787: If site is not authenticated, hide metadata form and user auth page.

Steps to reproduce

composer create-project drupal/recommended-project:9.5.11 9.5.11 && cd 9.5.11
composer config minimum-stability dev
composer require drupal/acquia_dam:1.1.x-dev drush/drush
./vendor/bin/drush site:install minimal --yes && ./vendor/bin/drush en acquia_dam --yes

Proposed resolution

The value for _acquia_dam_site_authenticated_access_check must be string here, but boolean value TRUE given. This is causing it to fail. But strangely, this is not failing on Drupal Core 10.x and above.
