Pull Request Overview

This PR adds automation for creating release notes for patch versions using GitHub Actions. The workflow generates changelogs by querying GitHub's API for backported pull requests and creates/updates GitHub releases with the generated notes and distribution assets.

Key changes:

• Adds a Gradle build script that queries GitHub API for backported PRs and generates markdown changelog
• Creates a GitHub Actions workflow that can be manually triggered to generate release notes and create GitHub releases
• Configures the launch module to use the new patch-specific build script

@wborn If this can be merged within the next 2 hours, I would directly use it for the 4.3.7 patch release. 😄

Please allow me to self-merge, so that we can test it!

Did it work? 🙂

It's nice to have it here. We should be able to automatically run it during releases when the rest of the pipeline is migrated.
