[JuHyung-Son]

Closes #828

for HF package, i use https://github.com/hupe1980/go-huggingface. i think this is more fit for k8sgpt code than this. Let me know if you think differently

ℹ Additional Information

Also, HF api request requires maxtokens less than or equal to 500. but k8sgpts default maxtokens is 2048 so users will get below output if they don't update or set maxtokens`.

How do you think setting huggingfaces default maxtokens to 500 if it is set k8sgpts default 2048?
