0.2 is not a breaking release for core (but it is for langchain and
community)
To keep the core+langchain+community packages in sync at 0.2, we will
relax deps throughout the ecosystem to tolerate `langchain-core` 0.2
**Description:** Adds chroma to the partners package. Tests & code
mirror those in the community package.
**Dependencies:** None
