FutureWarning for pandas date_range

[headtr1ck]

What is your issue?

Xarray raises a FutureWarning in its date_range, also observable in your tests.
The precise warning is:

xarray/coding/cftime_offsets.py:1130: FutureWarning: Argument closed is deprecated in favor of inclusive.

You should discuss if you will adapt the new inclusive argument or add a workaround.

Thanks for pinging this issue again in #7266 -- apologies for missing it earlier. I think we should adapt to the new inclusive argument and implement it for the cftime_range function as well.
