Initial GitHub Integration for the AI Mentor

[milesha]

Motivation

To make the AI mentor more engaging we want to integrate the GitHub data into its knowledge base.

Description

• The state of the graph now includes a dev_progress string, which saves the information about current GitHub PullRequests
• A new node is called in the beginning of the chat, when any PRs of the current user exist. It generates an overview of the PRs and asks the user if they want to add any of those to the final summary.

Smaller Updates:

• The SessionService "getSessions()" call now returns the sessions sorted by the creation date.
• Fix of the typo in the MentorResponse entity.

Testing Instructions

• Start intelligence-service, webapp and application-server
• Assign your user a mentor_access role
• Click on the "AI Mentor" button in the header and start your session:
• After the greeting you will receive a summary of your PRs of the last week.
• If you have and draft PRs the bot would reference them in the questions about impediments during the last sprint.
