[Bug]: Pandas warning causing test gallery errors

[rly]

What happened?

A new pandas warning about not having pyarrow installed is causing test_gallery.py to fail because it is set up to raise errors on unexpected warnings. See https://github.com/hdmf-dev/hdmf-zarr/actions/runs/7676572195

The warning says:

DeprecationWarning: 
Pyarrow will become a required dependency of pandas in the next major release of pandas (pandas 3.0),
(to allow more performant data types, such as the Arrow string type, and better interoperability with other libraries)
but was not found to be installed on your system.
If this would cause problems for you,
please provide us feedback at https://github.com/pandas-dev/pandas/issues/54466

We should just add this warning to the list of ignored warnings.

Steps to Reproduce

python test_gallery.py
