.github/workflows: trigger gitlab as soon as possible

Previously, we gated the GitLab tests on the unit tests. However, these now
take ~10 minutes, which is just annoying for engineers. This commit changes
the trigger to fire immediately after the PR is updated. This should save our
engineers 10 minutes on every push.

Regarding higher infra costs: Engineers are more expensive. :P
