text: Title: Ability to configure topic params in confluent create_topics
  Body: Currently if the topic doesn't exists we create it with `num_partitions` and `replication_factor` set to `1` - https://github.com/airtai/faststream/blob/7c069db7ff28bb43451aaa4dbffd84e8c261567a/faststream/confluent/client.py#L438-L452. We should provide a way for users to configure the `num_partitions` and `replication_factor` for each topic if possible.
