refactor: Update GitHub Actions workflow for release artifacts

This commit refactors the `build-desktop.yml` workflow to streamline the release process.

- Updates the `Check build output` step to correctly locate binaries in `composeApp/build/compose/binaries`.
- Replaces the `actions/upload-artifact` step with `softprops/action-gh-release`.
- Configures the new step to automatically upload build artifacts directly to a GitHub Release when a tag is pushed.
