I guess this is more in line of what is appropriate for this warning. Not sure about the exact wording.

Suggested change
Remove the `plannerVersion` option to use the default planner version, or specify a supported planner version.
Remove the `plannerVersion` option if the issue it was introduced for has been resolved, or contact Neo4j support for finding a different solution.
