The errors looks like this:

```python self = <xarray.backends.scipy_.ScipyArrayWrapper object at 0x00000234CBC43610> variable_name = 'dim2' datastore = <xarray.backends.scipy_.ScipyDataStore object at 0x00000234CBC43D90>

def __init__(self, variable_name, datastore):
    self.datastore = datastore
    self.variable_name = variable_name
    array = self.get_variable().data

  self.shape = array.shape

E AttributeError: can't set attribute

/home/runner/work/xarray/xarray/xarray/backends/scipy_.py:52: AttributeError ``` Setting shape like this doesn't seem like the proper way of doing it. Maybe these should just inherit NDArrayMixin as well?
