Himanshu Sharma ff12555bdc docs: clarify hub.pull behavior with non-US LangSmith endpoints (#31270)
**Description**:

This PR updates the documentation to address a potential issue when
using `hub.pull(...)` with non-US LangSmith endpoints (e.g.,
`https://eu.api.smith.langchain.com`).

By default, the `hub.pull` function assumes the non US-based API URL.
When the `LANGSMITH_ENDPOINT` environment variable is set to a non-US
region, this can lead to `LangSmithNotFoundError 404 not found` errors
when pulling public assets from the LangChain Hub.

Issue: #31191
