BUG: downstream testing breaks with minimal requirement on toolz #12162
Description
Describe the issue:
Using pytest.importorskip("dask.array") in an env that adheres to dask's current self-declared minimal requirements triggers an AttributeError from toolz 0.10.0
Minimal Complete Verifiable Example:
reproduced with toolz==0.10. pytest and numpy are also needed to reproduce the error

Anything else we need to know?:
The full context for this is that I'm trying to assess a truly minimal and reproducible testing environment for astropy + all of its optional and transitive dependencies.
