Change to Gitlab CI for testing

Ok. Giving this a go. A pipeline is running. The functional unit tests failed, which I am aware of before this. Curious to see how all of the lint testing goes.

The gitlab process is now running. There is work to do on the cspell job and phpcs and phpstan in our /tests directory. We will open additional issues for these.

Automatically closed - issue fixed for 2 weeks with no activity.
