[Bug]: Document API & Knowledge base document embedding issue

[nmilardo21]

Bug description

2 Issues when we try to upload the Document for knowledge base.

1. The API key (hardcoded) it takes for submitting document for embedding is being retrieved from the config.yaml and document.yaml

knowledge_extractor_config: options: model_name: "text-embedding-3-large" api_key: "xxxxxxxx"

2. After changing keys, it progressed further, and got error
   ERROR /app/app/core/embedding/plain_embedding.py 52 embed_documents app.core.embedding.plain_embedding Error in embedding documents: module 'app.bridges.artifacts.protos.integration_api_pb2_grpc' has no attribute 'CohereServiceStub'

Expected behavior

1. The key should be taken from the UI during creation of Knowledge Base.
2. The uploaded document should have been successfully embedded without giving any error.

Steps to reproduce

1. mac os -> docker
2. make up with knowledge base
3. create knowledge base, provide the API key (this key is not being considered during embedding).
4. upload documents.

Rapida version

v2.3.0
