Chroma: Replace existing documents with newer versions

I am planing to index our confluence wiki with go langchain. Therefore I had to be able to replace existing documents in chroma.

This needed the following changes:

Introcude a vectorstores.WithIDGenerater option and the according GenerateDocumentID func defaulting to uuid.NewString()
Use the new GenerateDocumentID func in chroma (and implemented to the best of my abilites for the rest of the stores).

While at it I realised that the chroma vectorstore did not call the Deduplicater so I fixed this as well.
