Set up GitLab CI

There needs to be a test for this to happen. Happy to accept any test coverage 😇.

I don't have any cycles to do much more than keep the lights on, as I no longer manage any live sites that use this module.

i have added gitlab-ci template and run all the pipeline.
please review it.
Thanks!!

Hello @chandansha
Could you modify your MR to target the 2.0.x branch which is the one used by the module?
Thanks
Marc

modified branch and added ci template.

The MR pipelines are presently failing.

A composer.json file is required for phpunit testing in Gitlab CI.

We also need to test on the previous major given Drupal 10 is still supported, so the gitlab CI template needs to be updated.
