chore(auto-tag): explicitly dispatch release workflow after tag creation

Add a step to trigger the release notes workflow after creating a version tag. This ensures that the release notes are generated even when the tag push does not automatically trigger the workflow due to GitHub's recursion guard.

Impact: Users will receive timely release notes corresponding to new version tags.
