CI: Update release drafter config (#588)

* Remove contributors section from release drafter template

The contributors section has been removed to simplify the release notes format. This change ensures a cleaner and more focused release draft template.

* Update release-drafter config with new labels and options

Added 'exclude-labels' to filter out 'no-changelog' items and improved category settings with 'collapse-after'. Introduced 'sort-by' for title-based sorting to enhance organization.
