Output behat results in format CircleCI likes for tests run on CI

[tauno]

Look at https://github.com/leymannx/drupal-circleci-behat/blob/develop/.circleci/config.yml#L86-L92 and try to do something similar. I believe this will output nicer test data in the CircleCI failure reports. Might require updating the robo-drupal test command.

Next steps

• [ ] Note that this is set up to happen on NCYL but has broken: https://app.circleci.com/pipelines/github/thinkshout/ncyl-ca/274/workflows/b79c1cdf-8f8b-4cc1-b32f-b6f675561a1d/jobs/303/tests so start by fixing that.
• [ ] Move the changes over to LVHN. There's a ticket that's related you can track time to: https://github.com/thinkshout/lvhn/issues/6050 -- My suspicion is that if we output behat tests in junit, we can also re-run only failed tests!
• [ ] Roll the out to changes required to robo-drupal (if any)
• [ ] If junit and only running failed tests works on LVHN, get a list of other sites using robo and behat and create tickets for each of those to use the new robo and behat to output junit. Add instructions on how to implement to those tickets.
• [ ] Update https://library.thinkshoutlabs.com/articles/new-site-setup-ticket-template-wordpress-and-drupal in the Behat section to include the changes needed to send behat results to junit.

These changes on NCYL https://github.com/thinkshout/ncyl/commit/829e2554bdf97da2a519772fea7117073910180f result in this nicer output of failures:

I've moved this to https://github.com/thinkshout/support/issues/78 so am closing.
