deprecated synthaxe to open tiff using xarray

Hello geoviews team,

ALL software version info

geoviews 1.9.5 pyhd8ed1ab_0 conda-forge geoviews-core 1.9.5 pyha770c72_0 conda-forge rioxarray 0.14.1 pyhd8ed1ab_0 conda-forge xarray 2023.5.0 pyhd8ed1ab_0 conda-forge Python 3.10.8 Ubuntu 22.04.2 LTS

Description of expected behavior and the observed behavior

geoviews.util.load_tiff() should open .tiff files. With xarray==2023.5.0 the syntaxe da = xr.open_rasterio(filename) is not valid anymore. see the code.

Complete, minimal, self-contained example code that reproduces the issue

to reproduce the issue you can download any .tiff file. I randomly fetch this one

In [1]: ff = '/tmp/file_example_TIFF_1MB.tiff'

In [2]: import geoviews as gv

In [3]: gv.load_tiff(ff)

While this file is readable with rioxarray for instance:
