AI Pull Request Summary:
The pull request modifies the GitHub Actions workflow file .github/workflows/review.yml, changing the pipeline from a general code review to a specific pull request summary and review process. Key changes include:

1. Workflow Name Change: Updated from "Code Review Pipeline" to "PR Summary and Code Review".

2. Event Types: Consolidated event types for pull requests into a list format.

3. Permissions: Added permissions for reading contents, writing pull requests, and writing issues.

4. Jobs Renaming: Renamed job from code_review to pr_summary.

5. Python Setup: Added steps for checking out the repository, setting up Python 3.9, and installing dependencies.

6. AI Summary Generation: Introduced a step to generate a summary of pull request changes using OpenAI's API, replacing the previous inline comment generation process. The new implementation fetches the PR diff, constructs a summary prompt, and posts the summary as a comment on the PR.

7. GPT Code Reviewer Integration: Added a separate job, code_review, using the PierreGode/GPTcode-reviewer action for comprehensive code review tasks, excluding certain file types like JSON and Markdown.

Overall, the changes simplify the workflow by focusing on summarizing pull request changes and utilizing an updated AI model for code reviews.
