hey there! Here's the guide on registering an integration package like this: https://python.langchain.com/docs/contributing/how_to/integrations/publish/#adding-documentation-to-the-langchain-monorepo

If you could fix it this week that would be great, as well as get it to pass CI

Hi @efriis . I followed the guide shared by you earlier & added the docs to Provider Page and Tools Page. However, I'm unsure about registering the package in libs/packages.yml because the package composio-langchain is developed and maintained by Composio, and the template for packages.yml requires specifying the path of the package.

Additionally, I'm encountering a lint error even before my changes were made in the master branch:

poetry run ruff check docs cookbook
All checks passed!
poetry run ruff format docs cookbook cookbook --diff
1151 files already formatted
poetry run ruff check --select I docs cookbook
All checks passed!
git --no-pager grep 'from langchain import' docs cookbook | grep -vE 'from langchain import (hub)' && echo "Error: no importing langchain from root in docs, except for hub" && exit 1 || exit 0
git --no-pager grep 'api.python.langchain.com' -- docs/docs ':!docs/docs/additional_resources/arxiv_references.mdx' ':!docs/docs/integrations/document_loaders/sitemap.ipynb' || exit 0 && \
        echo "Error: you should link python.langchain.com/api_reference, not api.python.langchain.com in the docs" && \
        exit 1

Could you please provide guidance on how to proceed with the registration in packages.yml & and fixing the lint error?
