Add support for Cohere Embed v3 Models

[bilgeyucel]

Is your feature request related to a problem? Please describe.
Cohere has a new type of embedding models: Embed v3. Let's add support for it for 2.0 pipelines
https://txt.cohere.com/introducing-embed-v3/
https://docs.cohere.com/reference/embed

Describe the solution you'd like
It seems like the only change we need to make in CohereEmbedder is to add the input_type parameter. See the documentation: https://docs.cohere.com/reference/embed

Describe alternatives you've considered
There's no other way of using these v3 models. When we pass the v3 model names, the CohereEmbedder (or cohere API, not quite sure which one) may not raise any error but the model fallbacks to a v2 model
