Chroma: Replace existing documents with newer versions

[vogtp]

I just realised I forked the wrong repo, please ignore

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.
