Update .gitlab-ci-unit-tests.yml CU-862k8dj8t

In order to use the new version of the image we need to update the pipelines. I tested this will work properly in two repos: https://gitlab.builder.ai/clientprojects/assembler_projects/prd/toddwarrengae-88612-ruby/-/jobs/26424702 https://gitlab.builder.ai/clientprojects/assembler_projects/prd/aaenterprisesearch-214637-ruby/-/jobs/26422928

which were repos with issues in completing the steps and this fully fixes their issue.

I could not first test on my repo because the unit test step fails on my mockup I think because I don't have any unit tests, please let me know what further test we need in order to merge this
