Pull Request Overview

This PR modernizes the release notes generation process by replacing custom JavaScript filtering logic with GitHub's native release notes configuration. The changes move from manual API calls and string manipulation to using GitHub's built-in generate_release_notes feature with a declarative configuration file.

• Replaces manual release notes generation and bot filtering with GitHub's native generate_release_notes parameter
• Adds a .github/release.yml configuration file to exclude bot accounts from release notes
• Simplifies the release workflow by removing custom JavaScript filtering logic

File	Description
.github/workflows/release.yml	Removes manual release notes generation code and enables GitHub's automatic generation
.github/release.yml	Adds release notes configuration to exclude bot authors from changelog

[Copilot]

The author exclusion list includes both 'costellobot' and 'costellobot[bot]'. Consider whether both entries are necessary, as GitHub typically uses the '[bot]' suffix for bot accounts. Review your repository's commit history to confirm which format is actually used.
