text: Title: test_dask_da_groupby_quantile not passing
  Body: ### What happened?
  
  The test fails because the expected `ValueError` is not raised:
  ```
  ________________________ test_dask_da_groupby_quantile _________________________
  [gw2] linux -- Python 3.13.0 /usr/bin/python3
  
      @requires_dask
      def test_dask_da_groupby_quantile() -> None:
          # Only works when the grouped reduction can run blockwise
          # Scalar quantile
          expected = xr.DataArray(
              data=[2, 5], coords={"x": [1, 2], "quantile": 0.5}, dims="x"
          )
          array = xr.DataArray(
              data=[1, 2, 3, 4, 5, 6], coords={"x": [1, 1, 1, 2, 2, 2]}, dims="x"
          )
  >       with pytest.raises(ValueError):

  /builddir/build/BUILD/python-xarray-2024.11.0-build/BUILDROOT/usr/lib/python3.13/site-packages/xarray/tests/test_groupby.py:295: Failed
  ```
  
  ### What did you expect to happen?
  
  Test pass.
  
  ### Minimal Complete Verifiable Example
  
  ```Python
  pytest 'tests/test_groupby.py::test_dask_da_groupby_quantile'
  ```
  
  
  ### MVCE confirmation
  
  - [X] Minimal example — the example is as focused as reasonably possible to demonstrate the underlying issue in xarray.
  - [X] Complete example — the example is self-contained, including all data and the text of any traceback.
  - [X] Verifiable example — the example copy & pastes into an IPython prompt or [Binder notebook](https://mybinder.org/v2/gh/pydata/xarray/main?urlpath=lab/tree/doc/examples/blank_template.ipynb), returning the result.
  - [X] New issue — a search of GitHub Issues suggests this is not a duplicate.
  - [X] Recent environment — the issue occurs with the latest version of xarray and its dependencies.
