Get project from langchain sdk (#13100)

Browse Source 
## Description
We need to centralize the API we use to get the project name for our
tracers. This PR makes it so we always get this from a shared function
in the langsmith sdk.

## Dependencies
Upgraded langsmith from 0.52 to 0.62 to include the new API
`get_tracer_project`
