Add GitLab CI template

Great thanks. I committed it however the tests are failing. Most likely it's because they were running with D9.5 before and now with D10.

Probably this line in RrssbTest.php line 54

$this->submitForm($edit, 'Save content type');

needs to change to this

$this->submitForm($edit, 'Save');

or something similar

Thanks! I'll try to fix this but I'll do it in a follow-up issue since the template is already committed.
