Since https://github.com/jenkinsci/jenkins/pull/3394 got merged tomorrow, now the way fingerprints are listed changed and https://github.com/jenkins-infra/evergreen/blob/612bb12b30325b5ded7a5ce6e8df830a74e87777/scripts/shim-startup-wrapper.sh#L10-L13 does not work anymore.

But now we can actually do it a more easily and cleanly, using the incremental repository http://repo.jenkins-ci.org/incrementals/org/jenkins-ci/main/jenkins-war/

So I'm going to use the maven-metadata.xml file there to find out the latest version, and then use the standard way to get checksum provided by artifactory to fix this. Could be less flaky overall, and anyway we do want to use incrementals in Essentials obviously.

Why now? Well, without this fix jenkins/evergreen does not even start anymore...
