IBX-6507: Adjustments for Solr and Elastic search engines

[micszo]

JIRA: IBX-6507

Two things are covered:

1. On Solr newly created user group is not found on first attempt when creating user:

     And I create a user group "SubtreeEditorsGroup"                                                           
     And I create a user "SubtreeEditor" with last name "Subtree Editor" in group "SubtreeEditorsGroup"      
       Ibexa\Core\Base\Exceptions\NotFoundException: Could not find 'User Group' with identifier 'SubtreeEditorsGroup' in vendor/ibexa/behat/src/lib/API/Facade/UserFacade.php:149

(e.g. https://github.com/ibexa/content/actions/runs/7300506772/job/19896363930?pr=106)

Loading User Group in User Facade is now retried few times every 0.5 second - 2e606f0.

2. Solr and Elastic config had to be added to multi repository setup - 175c3d0.

Depends on: ibexa/gh-workflows#48
