✨ feat: template a value in the topic name

[bmougeot]

🎯 This pull request aims to add dynamic management of topic names.

🤔 Why ? By allowing dynamic templates for topic names, we can replace parts of the topic with changing values. This will enable us to create unique topic names based on the environment (or other parameters), facilitating the testing of different conditions and scenarios with a single definition. _Example: we run tests on ephemeral environments where topic names include a reference to the corresponding pull request : pr-{pull_request_number}-topic-name_

💡 That’s why, since this feature exists in different HTTP steps, it would be useful to also have the ability to use templates for the topic names in Kafka.

🙏🏼 Thank you for taking the time to review these changes!
