Update composer dependency to accept ai@beta

Install patched version:

1. Modify composer.json - add repository:

           "drupal/ai_image_alt_text": {
               "type": "git",
               "url": "https://git.drupalcode.org/issue/ai_image_alt_text-3484955.git"
           },
   

2. Install branch package: composer require 'drupal/ai_image_alt_text:3484955-update-composer-dependency-dev'

Fixed this as part of initial release. Sorry for the delay.

Automatically closed - issue fixed for 2 weeks with no activity.
