community: allow chroma DB delete() to use "where" argument

[conjuncts]

Thank you for contributing to LangChain!

• PR title: "package: description"
  • Where "package" is whichever of langchain, community, core, experimental, etc. is being modified. Use "docs: ..." for purely docs changes, "templates: ..." for template changes, "infra: ..." for CI changes.
  • Example: "community: add foobar LLM"

Description: Simply pass kwargs to allow arguments like "where" to be propagated
Issue: Previously, db.delete(where={}) wouldn't work for chroma vectorstores
Dependencies: N/A
Twitter handle: N/A

• 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, hwchase17.

delete lets you pass where and where_document, but wouldn't passing additional kwargs cause an error? @baskaryan

Why is this fix only in the community version of the chroma vector store and not the official version?

The documentation for that module says its deprecated:
