What happened:

We have a failure related to a dask release, I think. Here's a job that failed: https://github.com/pydata/xarray/pull/5365/checks?check_run_id=2757459587

It's the test: xarray/tests/test_computation.py::test_vectorize_dask_dtype_meta

```

    # Input processing:
    ## Signature
    if not isinstance(signature, str):
        raise TypeError("`signature` has to be of type string")
    input_coredimss, output_coredimss = _parse_gufunc_signature(signature)

    ## Determine nout: nout = None for functions of one direct return; nout = int for return tuples
    nout = None if not isinstance(output_coredimss, list) else len(output_coredimss)

    ## Consolidate onto `meta`
    if meta is not None and output_dtypes is not None:

      raise ValueError(
            "Only one of `meta` and `output_dtypes` should be given (`meta` is preferred)."
        )

E ValueError: Only one of meta and output_dtypes should be given (meta is preferred).

```

Should we xfail this? Does anyone have thoughts for a quick fix?
