After the 2.402 release we are seeing an error when building on arm.

[ERROR] Step 'eclipse groovy formatter' found problem in 'Jenkinsfile':

Caused by: java.lang.IllegalArgumentException: Unknown os.arch aarch64'.

I had a quick peak at the differences this release https://github.com/jenkinsci/jenkins/compare/jenkins-2.401...jenkins-2.402

I looked like the related plugin version may have change https://github.com/jenkinsci/jenkins/compare/jenkins-2.401...jenkins-2.402#diff-9c5fb3d1b7e3b0f54bc5c4182965c4fe1f9023d449017cece3005d3f90e8e4d8R361 also some changes to the Jenkinsfile.  Not sure if related but figured I'd mention.  

I wonder if this is related to our build environment or could affect anyone building on arm?

For reference we are reverting the merge from our build https://github.com/wolfi-dev/os/pull/1583 note: we don't build CI on arm because of the terrible performance, which is why we are reverting a merge.
