Add testing configuration

Added .gitlab-ci.yml example file - there are some tests that need cleanup before configuring scheduled tests / tests on MR.

Failures are because of https://www.drupal.org/node/3030340 → needs to be handled.

Running properly now - the 2 failures appear to be 🐛 anchors add -01 Needs review

Setting to needs review on the assumption any changes to the test / logic for the failing tests should be handled in 🐛 anchors add -01 Needs review

Tests are now passing. This is achieved partially by disabling some of the tests.

I suggest that this be merged. With this merged, at least some testing will be in place to help with other issues. The tests that have been disabled can be fixed and re-enabled in a follow-up issue.

The commits should get a clean-up before merge. I am happy to do this. Maintainer, please let me know if you agree with the direction of this and I will do the clean-up.
