chore(deps): patch test dependencies

[Abhijeet Prasad (AbhiPrasad)]

Summary

• Bump the SDK CrewAI test lock from LiteLLM 1.88.0 to patched 1.88.6.
• Update the LangChain integration lock to virtualenv 21.14.5, resolving its four active advisories.
• The Bedrock example alert remains unmatched: its current pyproject.toml has no LiteLLM dependency, so there is no package pin to update there.

Validation

• uv lock --check in py/ and integrations/langchain-py/
• test_crewai(latest) under Python 3.13: 15 passed
• integrations/langchain-py: 2 tests passed
• git diff --check and repository pre-commit hooks passed
