This pull request focuses on enhancing the integration with Cohere's chat models by updating the available model list and ensuring the ChatCohere component is aligned with these new offerings.

Code Review

This pull request updates the list of available models for the ChatCohere node, removing older models and adding several new ones. The node version is also bumped to reflect these changes.

My review has identified two main issues:

1. The pricing information for the newly added Cohere models in models.json is incorrect. It appears the same placeholder values have been used for all new models, which do not reflect the official pricing for models like Command R and Command R+.
2. The default model in ChatCohere.ts has been changed to command-r-plus-08-2024, which is significantly more expensive than the previous default. This could lead to unexpected high costs for users.

I've provided specific suggestions to correct the pricing and to select a more cost-effective default model.
