Issue with `.sel` and `PintIndex` when using kwarg `method="nearest"`

I have tried using the latest version of pint-xarray==0.5.0 which includes units in the coordinates which is exciting but I believe I have found an issue when using .sel and the kwarg method="nearest", which would be used when selecting data nearest to the coordinate value specified but not exactly on the grid.

My guess is that the kwargs are not being passed correctly. Maintaining this functionality would be incredibly useful and hopefully an easy fix.

See a minimal working example below

import xarray as xr
import pint_xarray

ureg = pint_xarray.unit_registry
ds = xr.tutorial.open_dataset("air_temperature")
q = ds.pint.quantify({"lat": "degrees", "lon": "degrees"})

q_75 = q.sel(lat=75 * ureg.degrees)
q_74 = q.sel(lat=74 * ureg.degrees, method="nearest")

which fails with this error

Traceback (most recent call last):

TypeError: PintIndex.sel() got an unexpected keyword argument 'method'

Currently using pint-xarray=0.5.0 and xarray=2024.11.0.

See related issue here where this breaks our CI tests.

Start by running the minimal example with Python, xarray, and pint-xarray, then inspect the PintIndex.sel entry point reported in the traceback. The issue is done when q.sel(lat=74 * ureg.degrees, method="nearest") succeeds without the unexpected-keyword error and selects the nearest coordinate.
