1411125069,I_kwDOAMm_X85UHA9N,7177,xarray throws FutureWarning when using .interp method,12728107,closed,0,,,2,2022-10-17T08:21:42Z,2022-10-17T09:18:07Z,2022-10-17T09:18:07Z,NONE,,,,"### What happened?

I get a FutureWarning when using the .interp method on an xarray.DataArray

The issue is probably related to #6625, #5721 and #6195.

### Steps to reproduce

1. conda create -n test xarray scipy
2. conda activate test
3. python -c ""import xarray; xarray.DataArray([1., 2.]).interp(dim_0=0.5)""


### Expected output
Nothing


### Actual output

C:\Miniconda3\envs\test\lib\site-packages\xarray\core\missing.py:562: FutureWarning: Passing method to Int64Index.get_loc is deprecated and will raise in a future version. Use index.get_indexer([item], method=...) instead.
  imin = index.get_loc(minval, method=""nearest"")
C:\Miniconda3\envs\test\lib\site-packages\xarray\core\missing.py:563: FutureWarning: Passing method to Int64Index.get_loc is deprecated and will raise in a future version. Use index.get_indexer([item], method=...) instead.
  imax = index.get_loc(maxval, method=""nearest"")


### What did you expect to happen?

I expected no warning

### Minimal Complete Verifiable Example

```Python
import xarray
xarray.DataArray([1., 2.]).interp(dim_0=0.5)
```


### 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.

### Relevant log output

```Python
