fix(AI Agent Node): Fix tools agent when using memory and Anthropic models #10513

Merged

Summary

When using Anthropic models paired with memory, we discovered an issue with a Tools agent which would throw an error when populating the memory. To fix it, we need to checkAgentFinish step if it contains string or array output(in Anthropic's case) and merge the text-only array of outputs to a single item.

@burivuhster I've added a more detailed comment explaining what the handleAgentFinishOutput does. I also removed the langchain version updates and will do that in a tech-debt PR in conjunction with moving the versions to a catalog. Can you have one more look, please?
