MINOR: Improve printing topic name when created topic in TopicCommand (#14661) 

The topic name was displayed as `Optional<String>` when the topic was created.
```
% bin/kafka-topics.sh --create --topic test --bootstrap-server localhost:9092
Created topic Optional[test].
```
This PR fixed to print the topic name as `String` instead of `Optional<String>`.
```
% bin/kafka-topics.sh --create --topic test --bootstrap-server localhost:9092
Created topic test.
```
