Make the model display name the same as the model name

[sharunkumar]

For example, in groq, llama-3.1-70b-versatile is called Llama 3.1 70B in the dropdown menu, which could easily be confused with the other llama 70b models provided by groq. Naming it with the same name as the model name would make it more concise

To Reproduce
Steps to reproduce the behavior:

1. Make sure Groq API key is set
2. Click the Settings button
3. Select Groq as the provider
4. Open the Chat Models Drop Down

Expected behavior
The display name of the models should be the same as the models itself

I can work on a pr that addresses this, if it is good to go
