Enable .gitlab-ci.yml to the repository

Could you provide more details about this ? Why do you need it in the module?

Hello @minnur

Using GitLab CI in a contributed Drupal module plays a vital role in maintaining code quality, ensuring compatibility across environments, and automating the testing process. It supports continuous integration by automatically running tests, validating code changes, and enforcing coding standards whenever new code is pushed or a merge request is submitted. This helps identify issues early, streamlines the review process, and aligns with Drupal.org’s recommended development workflows.
