Description

When calling the REST endpoint to validate a connector configuration, the response includes duplicate values for the groups field:

{
  // ...
  groups: ["Common", "Transforms", "Common", "Transforms"]
}

This is a regression and may cause issues for any tooling that is using the Kafka Connect REST API.
