Pydantic <2.7.4 is broken on Python>=3.12.4 , see
https://github.com/pydantic/pydantic/issues/9609 .
Fixed upstream in https://github.com/pydantic/pydantic/pull/9639 .
Fix the following traceback in startup test on Python 3.12:
```

This is a bug caused in https://github.com/galaxyproject/galaxy/pull/18378 which made the `SaveChangesModal` useless because the version before the save was routed to.
Now, we instead append the version to the route after the user confirms the save (or doesn't) in the modal.
`input_step_parameters` that did not have labels (label=None) were being excluded in the `WorkflowInvocation.to_dict()` result.
This therefore sets the label to `n: Unnamed parameter` for null labels.
