Is your feature request related to a problem?

Currently we need to know the order of dims when using region in to_zarr. Generally in xarray we're fine with the order, because we have the names, so this is a bit of an aberration. It means that code needs to carry around the correct order of dims.

Here's an MCVE:

```python

ds = xr.tutorial.load_dataset('air_temperature')

ds.to_zarr('foo', mode='w')

ds.transpose(..., 'lat').to_zarr('foo', mode='r+')

ValueError: variable 'air' already exists with different dimension names ('time', 'lat', 'lon') != ('time', 'lon', 'lat'), but changing variable dimensions is not supported by to_zarr().

```

Describe the solution you'd like

I think we should be able to transpose them based on the target?
