Update the TEST_PARALLEL_JOBS value in CI

The authoritative source for this value is in the project's CI/CD
Variables Setting. The reason to keep it in .gitlab-ci.yaml as well is
to have functional testing in forks without the need to manually specify
this variable in Settings.

The tests have been executed with 4 jobs for some time now. This
"change" only brings .gitlab-ci.yaml file up to date, it doesn't
actually change the number of jobs we currently use to test.
