The "chromeOptions" array key is deprecated in drupal:10.3.0

Actually this is not under the control of this module. Looks like it should be done in gitlab_templates →

Gitlab templates has #3423154: Investigate if we need to change chromedriver →

Not sure if this was meant for this module but not sure if there's anything to change here.

Yes, nothing to change here. But when the gitlab_templates issue is fixed we should see the phpunit 'next minor' job pass again.
