Update testing configuration

Thanks a lot Liam (@Liam Morland) for raising this issue and sorry for the delay on this task.

Quick follow-up on this ticket:

Ported the last automated tests for the Supported D7 version of the module from Drupal QA to Gitlab CI by merging MR!53 into the 7.x-2.x branch above at #4 and pipeline came back green 🟢
https://git.drupalcode.org/project/block_class/-/pipelines/254454

After removing the last test for 7.x-2.x-dev on Drupal QA at:
https://www.drupal.org/node/246513/qa →
the page redirected to a 403 page with the following messages:

403 - Access denied

DrupalCI testing is deprecated. You cannot add new tests or edit existing ones.
Removed testing schedule.

Unfortunately, you don’t have permission to enter this area of the site.

 
Additionally, the Automated testing tab on module's project page has now disappeared, see:

At this point, Drupal QA should have been properly and completely decommissioned for this module and all its supported development branches configured to be tested on Gitlab CI at:
https://git.drupalcode.org/project/block_class/-/pipelines

At this stage, since all the tasks listed in the issue summary should have been completed, marking issue as Fixed for now.

Feel free to let us know if you have any questions or concerns on any of the latest changes, this ticket, or module's testing configuration in general, we would surely be glad to help.
Thanks in advance for your reviews and feedback!
