Keep up to date with recent pull requests

This function retrieves recent GitHub Pull Requests from a specified repository. It then classifies each pull request into predefined categories and generates a summary for each one. The final output is a markdown document that includes the title, category, and summary for each pull request.

What this workflow does

1. Fetch the three most recent GitHub Pull Requests from the specified repository.

2. Classify each pull request into categories such as New Feature, Bug Fix, Refactoring, Documentation, or Testing.

3. Generate a summary for each pull request based on its content.

4. Compile all the summaries and return it as the output.
