What happened?

The documentation for Dataset.to_zarr says that zarr_version is deprecated for zarr_format but calling DataArray.to_zarr with zarr_format throws an unexpected keyword exception, while calling it with zarr_version will raise a deprecation warning.

What did you expect to happen?

zarr_format should be a valid parameter

Minimal Complete Verifiable Example

import numpy as np
import xarray as xr

xr.DataArray(np.ones(3)).to_zarr("test", zarr_format=3)

MVCE confirmation

• Minimal example — the example is as focused as reasonably possible to demonstrate the underlying issue in xarray.
• Complete example — the example is self-contained, including all data and the text of any traceback.
• Verifiable example — the example copy & pastes into an IPython prompt or Binder notebook, returning the result.
• New issue — a search of GitHub Issues suggests this is not a duplicate.
• Recent environment — the issue occurs with the latest version of xarray and its dependencies.
