I suspect this commit has caused test failures in ZkControllerTest, see
[https://develocity.apache.org/scans/tests?search.rootProjectNames=solr-root&search.timeZoneId=Europe%2FOslo&tests.container=org.apache.solr.cloud.ZkControllerTest]
I believe it is a new test added. PR automated tests fail due to this.

> This proposal is for the "live node" (ZkController.createEphemeralLiveNode)
> stored in ZK to have a JSON payload with the SolrVersion and other
> interesting metadata like the node roles. Furthermore, ZkStateReader should
> read this state and provide a method like getLowestSolrVersion().
> This foundational mechanism allows us to evolve SolrCloud safely using an
> in-place rolling upgrade strategy. Features that need to behave differently
> can consult the lowest SolrVersion to react accordingly.
