box: Add citation support to langchain_box.retrievers.BoxRetriever when used with Box AI

[shurrey]

Thank you for contributing to LangChain!

Description: Box AI can return responses, but it can also be configured to return citations. This change allows the developer to decide if they want the answer, the citations, or both. Regardless of the combination, this is returned as a single List[Document] object.

Dependencies: Updated to the latest Box Python SDK, v1.5.1
Twitter handle: BoxPlatform

• Add tests and docs: If you're adding a new integration, please include

  1. a test for the integration, preferably unit tests that do not rely on network access,
  2. an example notebook showing its use. It lives in docs/docs/integrations directory.

• Lint and test: Run make format, make lint and make test from the root of the package(s) you've modified. See contribution guidelines for more: https://python.langchain.com/docs/contributing/

Additional guidelines:

• Make sure optional dependencies are imported within a function.
• Please do not add dependencies to pyproject.toml files (even optional ones) unless they are required for unit tests.
• Most PRs should not touch more than one package.
• Changes should be backwards compatible.
• If you are adding something to community, do not re-import it in langchain.

If no one reviews your PR within a few days, please @-mention one of baskaryan, efriis, eyurtsev, ccurme, vbarda, hwchase17.
