Simplify release workflow

[martincostello]

With #2678, the release draft can be created in one request, rather than generating the notes and then manually editing them first.

Pull Request Overview

This PR simplifies the GitHub release workflow by leveraging the native generate_release_notes feature instead of manually generating and filtering release notes. The change reduces code complexity by removing manual note generation and filtering logic.

• Replaces manual release note generation with GitHub's built-in generate_release_notes parameter
• Moves bot exclusion logic from JavaScript filtering to the .github/release.yml configuration file
