fix: add Groq Model Constants

[edwinjosechittilappilly]

This solves the issue temporarily for the GROQ Models not visible in Agent Component.

This pull request includes updates to the GroqModel class and its associated constants to improve the handling of model names and simplify the codebase. The most significant changes involve the introduction of a new GROQ_MODELS constant and the removal of unnecessary methods for fetching model names dynamically.

Updates to model constants and usage:

• src/backend/base/langflow/base/models/groq_constants.py: Introduced a new constant GROQ_MODELS to replace the old MODEL_NAMES list and ensure reverse compatibility.

Simplification of GroqModel class:

• src/backend/base/langflow/components/models/groq.py: Updated the GroqModel class to use the new GROQ_MODELS constant for the options parameter in the DropdownInput field.
• src/backend/base/langflow/components/models/groq.py: Removed the get_models method and the update_build_config method, as the model names are now statically defined in the GROQ_MODELS constant.

These changes streamline the code, making it easier to maintain and reducing the need for dynamic fetching of model names.
