Ensure the in-project venv gets cached in CI tests. (langchain-ai#9336)

The previous caching configuration was attempting to cache poetry venvs
created in the default shared virtualenvs directory. However, all
langchain packages use `in-project = true` for their poetry virtualenv
setup, which moves the venv inside the package itself instead. This
meant that poetry venvs were not being cached at all.

This PR ensures that the venv gets cached by adding the in-project venv
directory to the cached directories list.

It also makes sure that the cache key *only* includes the lockfile being
installed, as opposed to *all lockfiles* (unnecessary cache misses) or
just the *top-level lockfile* (cache hits when it shouldn't).
