Add 'LLM Knowledge Distillation' to Readme or Topic Tags

[Elijas]

Hello,

The concept of 'LLM Knowledge Distillation', intrinsic to gpt-llm-trainer, isn't explicitly highlighted in the repository. Adding it to the Readme or the Github Topic Tags could introduce multiple benefits. It could help users understand the core mechanism employed and enhance the discoverability of this repository for those seeking similar solutions.

Thanks for considering my suggestion!
