using Groq API (or RedPill or Google Gen AI) as model provider

[YoungPhlo]

Describe the bug

trying to use the Groq API but its not clear how to define the model in the .env file. other providers have SMALL_HEURIST_LANGUAGE_MODEL, SMALL_HEURIST_LANGUAGE_MODEL, etc

I'm not sure how to define the model in the .env file

To Reproduce

https://github.com/ai16z/eliza/blob/main/.env.example

Expected behavior

Something similar to Heurist SMALL_GROQ_LANGUAGE_MODEL= MEDIUM_GROQ_LANGUAGE_MODEL= LARGE_GROQ_LANGUAGE_MODEL=

Additional context If not custom .env variables at least a nod in the right direction my IDE pointed me to packages/core/src/models.ts
