docs: Gets {@link Properties} from a {@link WorkUnitState} and sets the config <code>schema.registry.url</code> to value
  of {@link KafkaSchemaRegistry#KAFKA_SCHEMA_REGISTRY_URL} if set. This way users don't need to specify both
  properties as <code>schema.registry.url</code> is required by the {@link ConfluentKafkaSchemaRegistry}.
