py-xarray: updated to 2024.1.1

v2024.01.1 (23 Jan, 2024)

This release is to fix a bug with the rendering of the documentation, but it \ 
also includes changes to the handling of pandas frequency strings.

Breaking changes

- Following pandas, :py:meth:`infer_freq` will return ``"YE"``, \ 
instead of ``"Y"`` (formerly ``"A"``).
  This is to be consistent with the deprecation of the latter frequency string \ 
in pandas 2.2.

Deprecations

- Following pandas, the frequency string ``"Y"`` (formerly \ 
``"A"``) is deprecated in
  favor of ``"YE"``. These strings are used, for example, in \ 
:py:func:`date_range`,
  :py:func:`cftime_range`, :py:meth:`DataArray.resample`, and \ 
:py:meth:`Dataset.resample`
  among others (:issue:`8612`, :pull:`8629`).

Documentation

- Pin ``sphinx-book-theme`` to ``1.0.1`` to fix a rendering issue with the \ 
sidebar in the docs.
