DEPS: Filter numpy's FutureWarning from array_equal
Looks to be failing on the numpy dev build

The warning is from `np.array_equal` raising it's own FutureWarning: https://github.com/numpy/numpy/issues/23401
LGTM pending green Looks like the numpy dev build is installing a non-numpy dev version for some reason: https://github.com/pandas-dev/pandas/actions/runs/4432829243/jobs/7777266394

`Requirement already satisfied: numpy>=1.21.0 in /home/runner/micromamba/envs/test/lib/python3.10/site-packages (from pandas==2.1.0.dev0+239.g69b7019c10) (1.24.2)` Looked to have been an environment solve/cache issue, but I suppose this could be useful to still filter this out. The 2.0.x build is still failing as of this morning, so merging and backporting thx @mroeschke  Purging the cache there helped as well
