kafka KAFKA-18061 AddRaftVoter responds with error message "NONE" instead of null

Fix building 'Response.errorMessage' with 'RaftUtil #addVoterResponse' and' RaftUtil#removeVoterResponse' for 'Errors.NONE' is not 'null' but 'NONE' because When 'errorMessage' is passed in as 'null', 'Errors#message' is used to generate a default value, and this method is a friendly result.

Summary of testing strategy (including rationale) for the feature or bug fix. Unit and/or integration tests are expected for any behaviour change and system tests should be considered for larger changes.
