KIP-569 — DescribeConfigsResponse - Update the schema to include additional metadata information of the field

Accepted Kafka 2.6 ProtocolAdmin

Extends the `DescribeConfigsResponse` schema to include additional metadata per configuration entry: `type` (string, int, boolean, etc.), `documentation`, and `validValues`, alongside the existing `isSensitive`/`isReadOnly` fields. GUI tools like Confluent Control Center and Lenses need config type and validation metadata to render appropriate input controls and prevent invalid submissions without requiring hardcoded knowledge of each config.
