Fix test_xfail_behavior with pytest 7.2.0+

[swt2c]

In pytest-dev/pytest@69fb79e, pytest output was changed to include the reason string on the same line as the short test summary, so the test needs to be updated correspondingly.

Looks good to me! A few notes:

• GH action no longer supports Python 3.6, if you want to test with it, take a look at https://github.com/fedora-python/tox-github-action
• The latest pytest does not support Python 3.6 so the tox.ini also needs an update.
• It would be nice to have a new release with this fix because the latest one is almost a year old.

I did a manual test locally and it seems that it works well. Thank you!

On your first two bullets - yep, see #75

I suggest we just cherry-pick 8d722cb on top of #75 and merge that PR. 👍

Done.

FYI it is possible to get 3.6 in GHA if you set runs-on to an older Ubuntu.
