docs: Update Google El Carro for Oracle Workload Documentation. (lang…

…chain-ai#18394)

In this commit we update the documentation for Google El Carro for Oracle Workloads. We amend the documentation in the Google Providers page to use the correct name which is El Carro for Oracle Workloads. We also add changes to the document_loaders and memory pages to reflect changes we made in our repo.
