Update to Gemini exp-1121

Just saw that Google has updated their experimental model so I had to update it here as well.

@kekePower Could you kindly add these Hugging Face models to the constants file? Place them below the Qwen-32B-Instruct model. The models to add are:

• Qwen/Qwen2.5-72B-Instruct
• meta-llama/Llama-3.1-70B-Instruct
• meta-llama/Llama-3.1-405B

We can do another PR for that.
Honestly I wanted to invest in to dynamic loading of models better for number of reasons, so that we do not need to make such PRs at all

Sure, that sounds good. Yes, a dynamic approach is much better, especially with so many models and new places offering attractive pricing or even free options.
