Subject: [PATCH] Fix: Extend pyproject.toml check in create_api_rst.py to
 langchain/libs folder (#31128)

- **Description:** The file ```docs/api_reference/create_api_rst.py```
uses a pyproject.toml check to remove partners which don't have a valid
pyproject.toml. This PR extends that check to ```/langchain/libs/*```
sub-directories as well. Without this the ```make api_docs_build```
command fails (see error).
- **Issue:** #31109
- **Dependencies:** none
- **Error Traceback:**
uv run --no-group test python docs/api_reference/create_api_rst.py
