chore: add Discord notification action for release announcements

- Beat EDACerton to the punch
- Integrated a new action in the release workflow to send notifications to a Discord channel upon new releases.
- The notification includes the release version, a link to the release, and the changelog, enhancing communication with users.

This addition improves user engagement by providing timely updates on new releases directly in Discord.
