Fix broken ImageRescaleWrapper due to PIL's resize() change.

PIL 10.4.0's `Image.resize()` behavior causes a breakage in
`ImageRescaleWrapper` due to the way numpy arrays are compared. In particular,
in 10.3.0 the `size` argument was cast to a `tuple`, but not in 10.4.0 (see
[changes](python-pillow/Pillow@10.3.0...10.4.0)).
This has since been
[reinstated](python-pillow/Pillow@936012e),
but it did not make it to the 10.4.0 release.

We can still change our code though, so we now simply pass a `tuple` instead of
an `np.array`.
