in the latest xarray version 2022.06.0, xarray.DataArray.quantile supports 9 methods:
https://docs.xarray.dev/en/latest/generated/xarray.DataArray.quantile.html

however, those methods are only implemented starting from numpy  1.22.0 
https://numpy.org/doc/stable/reference/generated/numpy.quantile.html

whereas the current numpy requirement is only numpy >= 1.19

### What did you expect to happen?

that the numpy requirement is updated to numpy >= 1.22

### Minimal Complete Verifiable Example

_No response_

### 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](https://mybinder.org/v2/gh/pydata/xarray/main?urlpath=lab/tree/doc/examples/blank_template.ipynb), returning the result.
- [ ] New issue — a search of GitHub Issues suggests this is not a duplicate.
