This won't work, pyiron_workflow doesn't currently support 3.14

And those run on the requested version of python (which is not 3.14). Indeed, even if the tests did exists and were all running, you'd still have needed to go into the test suite and instructed it to cover the new python version in its matrix in order to have gotten a failure.
