Change prompt to try and get only topic names

[abhinavg4]

Description

Tries to fix #533. LLM gives output topics with descriptions. When we try to create a YAML, those descriptions sometimes get treated as separate topics. We modify the prompt to ask the LLM to just give the topic list.

Usage

Hi yes, it works. But I said "try" since it's model-dependent.
