There was a problem hiding this comment.
This was previously inadvertently filtering on the initial_freq rather than the resample_freq...
By coincidence that happened to be OK given the set of frequency pairs that we were filtering and the pandas behavior at the time, but that is not the case anymore. This fixes that bug.

Description
Pandas is rolling back a change we adapted to about a year ago (#10650) related to resampling with a
Dayfrequency (pandas-dev/pandas#64793). This PR makes the necessary changes in xarray to do the same.This addresses some of the upstream failures surfaced in #11501.
