chore: update langgraph latest version to 0.6.8 (#14775)

Update langgraph lockfiles and dependency package lockfiles.
This performs the following updates:
1) Some langgraph lockfiles use langgraph `latest`. This will update
langgraph and dependencies.
2) Some langgraph lockfiles use a pinned (non-latest) version of
langgraph, but require the `latest` version of another package. This
will update all such packages.
