[gmx-developers] Please cancel outdated CI pipelines

Given that several other test containers finish in ~2 minutes, I think it's
relatively unlikely that random fluctuating resource contention would
systematically always affect the gmxapi test every time it is run, but no
other jobs :-)

The whole point of k8s/docker is that the runtime environment is
standardized; what performance do you see if you run the same container
e.g. on your laptop, desktop, or any other cloud resource when assigning
two hardware threads to it?
