[Releases/2.22] Add new parameters for context documents and ease queryTensor restriction

[wanliAlex]

Change Summary

This pull request introduces improved handling of missing documents and embeddings in recommendation and search workflows. It adds new parameters to allow the API to optionally skip errors when documents or their embeddings are missing.

In addition, we ease the restriction on the hybrid parameters queryTensor. It can now be either None, {} or even nothing. Marqo will raise an error if it can not collect any vector from the inputs while a vector is needed.
