Add api-key support to InfitityEmbeddings

• I've clearly described the feature request and motivation for it

Feature request

Infinity Embeddings Inference Server does support the creation of API-Keys (see here). The InfinityEmbeddings implementation does not seem to support this feature yet. Trying to add an api-Key to the function creates the error:

  Extra inputs are not permitted [type=extra_forbidden, input_value='meinapikey', input_type=str]
    For further information visit https://errors.pydantic.dev/2.9/v/extra_forbidden

This relates to the langchain.embeddings.infinity.InfinityEmbeddings class, which originates from the langchain-community version.

Motivation

Infinity is a really cool embedding inference service and a better integration into Langchain would make it a more viable alternative.
