org.elasticsearch.xpack.core.ml.job.config.JobUpdateTests > testMergeWithJob FAILED
    java.lang.IllegalArgumentException: Cannot convert 8.11.0. Incompatible version

```

With all these "versions" that we have now decoupled from transport version or node version, we need to ensure that all get bumped when a version bump occurs. There are too many of these things to not catch them in CI in a version bump for a cut release.
