feat: Update release body and add changelog to release notes

This commit updates the release body to a static message and adds the changelog to the release notes.

The `body_path` parameter in the `softprops/action-gh-release` action is replaced with a static message. A new step is added to update the GitHub release with the generated changelog using the GitHub CLI. This ensures the changelog is included in the release notes.
