Fix/document embeddings (#247)

* Update schema for doc embeddings

* Rename embeddings-vectorize to graph-embeddings

* Added document-embeddings processor (broken, needs fixing)

* Added scripts

* Fixed DE queue schema

* Add missing DE process

* Fix doc RAG processing, put graph-rag and doc-rag in appropriate component files.
