TST: update xfail xarray version check in to_xarray test

[jorisvandenbossche]

Started to see xpass in #61594, so updating the version check here. Not sure this is entirely covered by CI, but tested this locally with a few different xarray versions.

Owee, I'm MrMeeseeks, Look at me.

There seem to be a conflict, please backport manually. Here are approximate instructions:

1. Checkout backport branch and update it.

git checkout 2.3.x
git pull

2. Cherry pick the first parent branch of the this PR on top of the older branch:

git cherry-pick -x -m1 7def76a79361c8f6aa2893d9a559da03c6cb6d3a

3. You will likely have some merge/cherry-pick conflict here, fix them and commit:

git commit -am 'Backport PR #61648: TST: update xfail xarray version check in to_xarray test'

4. Push to a named branch:

git push YOURFORK 2.3.x:auto-backport-of-pr-61648-on-2.3.x

5. Create a PR against branch 2.3.x, I would have named this PR:

"Backport PR #61648 on branch 2.3.x (TST: update xfail xarray version check in to_xarray test)"

And apply the correct labels and milestones.

Congratulations — you did some good work! Hopefully your backport PR will be tested by the continuous integration and merged soon!

Remember to remove the Still Needs Manual Backport label once the PR gets merged.

If these instructions are inaccurate, feel free to suggest an improvement.
